Who Dares Wins, also known as The Final Option, is a 1982 British political thriller film directed by Ian Sharp and starring Lewis Collins, Judy Davis, Richard Widmark, Tony Doyle, and Edward Woodward. The film is loosely based on the actions of the British Army's Special Air Service (SAS) in the 1980 Iranian Embassy siege; however, the plot makes considerable fictionalised departures from the actual siege and its background, and instead follows SAS Captain Peter Skellen as he infiltrates a terrorist group planning an attack on American diplomats. The film's title references the motto of the SAS.

Lewis Collins was an English actor, best known for his career-defining role playing 'Bodie' in the late 1970s – early 1980s British television series The Professionals.
