Every year brings a fresh group of celebrities who suddenly seem to be everywhere. Some have already spent years working behind the scenes or appearing in smaller roles, while others seem to arrive almost overnight with a song, movie, television series, or unforgettable performance that captures public attention.
Looking back at 2014, several entertainers experienced that defining moment when their careers moved to an entirely new level. From rising musicians dominating the charts to young actors landing major film and television roles, these stars proved that one successful project can completely change the trajectory of a career.
A breakout year does not necessarily mean someone was completely unknown before. In many cases, these performers had already been working steadily for years. What made 2014 different was the combination of major opportunities, public recognition, critical praise, and projects that introduced them to much larger audiences.
With another year beginning, the future looked bright for many of these rising stars. Some would go on to become major Hollywood names, while others would continue developing their careers in unexpected directions. Here are 12 of the most memorable breakout stars associated with 2014.
Ariana Grande
Ariana Grande had already gained a loyal following through her Nickelodeon appearances, particularly on Victorious and Sam & Cat. However, 2014 was the year she successfully transformed herself from a young television performer into one of pop music's most recognizable new stars.
Her second studio album, My Everything, produced a series of major hits, including “Problem,” “Break Free,” and “Bang Bang.” The songs received extensive radio and chart exposure and helped establish Grande as a serious force in contemporary pop music.
Her distinctive high-range vocals, energetic performances, and rapidly growing fan base made her one of the year's most talked-about young entertainers. Her public profile also grew considerably as her personal life and celebrity relationships attracted additional media attention. By the end of 2014, it was clear that Grande's career had moved well beyond her early television work.
Dylan O’Brien
Dylan O’Brien had already built a strong teenage following through MTV's Teen Wolf, but his career took a major step forward in 2014. His role as Thomas in the film adaptation of James Dashner's The Maze Runner introduced him to a much broader international audience.
The science-fiction adventure became a commercial success and demonstrated that O’Brien could carry a major motion picture. His performance received positive attention, and the success of the movie quickly created expectations for the next chapter in the franchise.
With his television popularity combined with a successful film role, O’Brien suddenly found himself being mentioned among Hollywood's promising young actors. The opportunity showed that he had the potential to move comfortably between television and big-screen projects.
Meghan Trainor
Few new artists had a bigger breakthrough in 2014 than Meghan Trainor. Her debut single, “All About That Bass,” became an international phenomenon and transformed the young singer-songwriter into one of the year's most recognizable new pop performers.
The song topped charts across numerous countries and stood out for its retro-inspired production, catchy melody, and message about body confidence. Its enormous popularity helped Trainor establish a distinctive identity at a time when the pop music landscape was already crowded with established stars.
Her success also generated considerable industry attention ahead of her debut album. With major artists praising her songwriting and personality, Trainor entered 2015 with considerable momentum and a strong foundation for a long-term music career.
Chris Pratt
Chris Pratt had been a familiar face to television audiences for years thanks to his role as Andy Dwyer on Parks and Recreation. In 2014, however, he made the dramatic transition from beloved television comedian to major Hollywood leading man.
His starring role as Peter Quill in Guardians of the Galaxy changed everything. The Marvel movie became one of the year's biggest box-office successes, while Pratt's combination of comedy, action, and charisma made him a standout performer.
The transformation was particularly impressive because Pratt had previously been known primarily for comedic roles. His success demonstrated that audiences were willing to embrace him as an action star as well. With several major projects already ahead of him, his career appeared to be entering an entirely new phase.
Iggy Azalea
Australian rapper Iggy Azalea became one of the biggest new names in hip-hop during 2014. Her breakthrough single “Fancy,” featuring Charli XCX, became a huge international hit and dominated radio and music charts.
Her debut album, The New Classic, further established her presence in mainstream music. She also appeared on major collaborations, including songs with Ariana Grande, Jennifer Lopez, Rita Ora, and T.I.
Azalea's rapid rise brought both praise and controversy. Her music, image, collaborations, and public disagreements with other artists regularly generated headlines. Regardless of the debate surrounding her, there was little question that she had become one of the year's most visible new music stars.
Shailene Woodley
Shailene Woodley was not an unknown actress when 2014 began. She had already developed a following through television, but that year dramatically increased her profile and established her as one of Hollywood's most promising young leading actresses.
She played Tris Prior in the science-fiction adventure Divergent, giving her the opportunity to lead a major young-adult franchise. She also delivered a memorable performance as Hazel Grace Lancaster in the emotional drama The Fault in Our Stars.
The combination of two successful films gave Woodley considerable momentum. Her performances earned critical attention, magazine covers, and a growing international fan base, making 2014 an important turning point in her career.
Alfred Enoch
Many viewers first encountered Alfred Enoch as Dean Thomas in the Harry Potter film series. However, 2014 gave him an opportunity to step into a much more prominent role when he joined the cast of Shonda Rhimes' legal drama How to Get Away With Murder.
Enoch played Wes Gibbons, one of the central characters in the series. The show's mystery-driven story and talented ensemble quickly attracted a large audience, giving Enoch considerably more exposure than he had received from his earlier work.
His performance demonstrated that he could handle a complex television role and helped establish him as a performer worth watching. The success of the series also gave him an excellent platform for future opportunities.
Gina Rodriguez
Gina Rodriguez became one of television's most exciting new stars in 2014 thanks to her leading role in Jane the Virgin. Although she had already accumulated acting credits before the series, this role introduced her to a much wider audience.
The CW comedy-drama quickly earned praise for its unusual premise, humor, emotional storytelling, and Rodriguez's charismatic performance. Her portrayal of Jane demonstrated a wide range and made her one of the show's biggest attractions.
The success of the series also brought Rodriguez major awards attention and established her as an important new television talent. Her performance made 2014 a defining year and created plenty of anticipation for what she would do next.
Ansel Elgort
Ansel Elgort's career accelerated dramatically in 2014. After making his film debut in the previous year's Carrie remake, he landed roles in two highly successful young-adult film adaptations.
He played Augustus Waters opposite Shailene Woodley in The Fault in Our Stars, a romantic drama that became a major box-office success. He also appeared alongside Woodley in Divergent, where he portrayed her character's brother Caleb.
Having major roles in two popular movies during the same year gave Elgort remarkable exposure. His youthful appeal and growing acting profile quickly made him one of the young performers Hollywood audiences were beginning to watch closely.
Finn Wittrock
Finn Wittrock delivered one of the most memorable breakthrough performances of 2014 with his role as Dandy Mott in American Horror Story: Freak Show. The character was disturbing, unpredictable, and deliberately unsettling, giving Wittrock an opportunity to showcase a dramatically different side of his acting ability.
Originally expected to appear in a smaller storyline, his character became increasingly important as the season progressed. Wittrock's performance attracted considerable attention and helped establish him as an actor capable of making a lasting impression.
Before American Horror Story, Wittrock had already built experience through stage performances, television work, and film appearances. His success in the series, along with his role in Unbroken, helped move his career toward a much larger audience.
Jenny Slate
Jenny Slate had already gained attention as a comedian and performer, but 2014 helped demonstrate that she could make a significant impact as a dramatic actress as well. Her independent film Obvious Child became one of the year's most talked-about smaller releases.
Slate's performance received strong reviews and helped shift the public's perception of her beyond her earlier comedy work. The film showcased her ability to combine humor with emotional depth and gave her considerable attention during awards season.
She also continued working in television, including her role in the FX comedy series Married. Her growing collection of film and television projects made 2014 an important stage in the development of her career.
Sam Smith
Sam Smith was another musician whose career exploded during 2014. The English singer had already attracted attention through collaborations with electronic music artists, but his debut album, In the Lonely Hour, established him as a major solo performer.
The album produced several internationally successful songs and showcased Smith's distinctive, soulful voice. His emotional songwriting and vulnerable performances helped him connect with listeners across different markets.
By the end of the year, Smith had become one of the most celebrated new voices in popular music. His growing chart success, award nominations, and international recognition suggested that his breakout year was only the beginning of a much larger career.
