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: Robert made his professional debut in a Radio 4 series called Injury Time, going on to take a small role in the first episode of Red Dwarf, and also appearing on stage in Noises Off. He made more of a splash with sitcom Joking Apart, which he has described as his favourite role, but it was winning the part of David in comedy drama Cold Feet in 1996 that really made him a star. Since then, he's continued to be in demand on stage and TV, appearing in My Dad's the Prime Minister, Downton Abbey and The Pillars of the Earth, and playing John Le Mesurier in Hattie. He was also reunited with his Cold Feet co-star Hermione Norris for a production of Blithe Spirit. Recently, he has been playing Lord Thomas Davenport in TV horror drama Dracula.
