Career: Early projects included A Relative Stranger, Poldark and Wilde, but it was his small part as Fifth Officer Lowe in James Cameron's blockbuster Titanic that got him noticed. The title role in miniseries Hornblower followed, making Gruffudd a star on both sides of the Atlantic. He impressed in the BBC's adaptation of Great Expectations, drama Solomon and Gaenor (for which he learned Yiddish) and children's hit 102 Dalmatians, before reprising Hornblower. He's also appeared in The Forsyte Saga, Man and Boy, Warriors and Ringer, and his healthy film career has included the movies Fantastic Four (and its sequel), Black Hawk Down, and historical drama Amazing Grace. In 2014, he began playing Dr Henry Morgan in American crime drama Forever.

Career: Lindsay's movie debut came in 1973's That'll Be the Day. His big break came in 1977 when he played would-be revolutionary Wolfie in John Sullivan's BBC sitcom Citizen Smith. After that he concentrated on serious roles. Theatre parts include Hamlet and Cyrano De Bergerac, but his biggest stage hit to date is musical Me and My Girl, for which he won numerous awards on both sides of the Atlantic. He made his Hollywood debut in the ill-received Bert Rigby You're a Fool in 1989, but Alan Bleasdale's TV series GBH put his career back on track. Since then, successes include Jake's Progress, The Wimbledon Poisoner, Brazen Hussies, Hornblower and My Family. More recently, he's starred in detective drama Jericho, played Tony Blair in A Very Social Secretary and The Trial of Tony Blair, traced his family on Who Do You Think You Are? and starred in Sky1 sitcom Spy.

Career: Antony got his break at the Everyman Theatre in Liverpool in the early 1970s, where his contemporaries included Julie Walters and Jonathan Pryce, and landed the role of Ringo Starr in Willy Russell's John, Paul, George, Ringo and Bert. TV fame came in 1981 when he played the lead in the series The History Man, and he has gone to appear in the likes of The Jury, God on Trial, and The Shadow Line as well as movies such as The Wind in the Willows and Three and Out. However, his best-known work has been on the stage, and he won the prestigious Olivier Award for Richard III in 1985 and then again for Stanley in 1997. He was knighted in 2001, and in recent years has also returned to his first love, painting.

Career: West had a small part in TV series Nanny when he was 13, but didn't become hooked on acting until appearing with Oxford University's theatre group. He went on to appear in a TV adaptation of the Chronicles of Narnia as Prince Caspian, but 1992's Howards End was his big break, earning him a Bafta nomination for Best Supporting Actor. Since then he's appeared in A Feast at Midnight, Carrington, Persuasion, Jane Eyre, Stiff Upper Lips, Hornblower, Iris, and Van Helsing. He also starred in the critically acclaimed play ENRON in 2009 and alongside his father in Caryl Churchill's two-hander A Number, in 2011.
