British actor Chiwetel Eljiofor played a more peripheral character, Peter, who gets married to Knightley in the film's wedding scene. But he earned much more attention, and an Oscar nomination, for playing Solomon Northup in Steve McQueen's 12 Years a Slave.Universal; Getty Images

Colin Firth, who played Uncle Jamie, was already a heartthrob when Love Actually came out, having played Mr. Darcy in the BBC's Pride and Prejudice and then a Mr. Darcy variety in Bridget Jones' Diary. But after 2003, he has also continued to reap critical praise, picking a variety of films, from the Oscar-winning The King's Speech to Woody Allen's recent Magic in the Moonlight.Universal; Getty Images

Widely respected thespian Emma Thompson has gone to great lengths for her film and television roles, which have earned her two Oscars and an Emmy--but for Love Actually she actually had to wear a fat suit to play her character.

She also made headlines after announcing Best Screenplay at the Golden Globes barefoot with a martini in hand. Universal; Getty Images

He went on to greater fame as Severus Snape in the Harry Potter series. He recently directed and starred in A Little Chaos, about designing a fountain at Versailles, that will hit theaters in the UK in April of 2015.Universal; Getty Images
