Who Dares Wins 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 title is the motto of the British Army’s elite Special Air Service (SAS). The plot is based largely on the Iranian Embassy siege of 1980 in London, when a team from the SAS made a sudden assault on the building to rescue those being held hostage inside. As producer, Euan Lloyd was inspired to make the film by visiting the scene during the siege and watching live coverage of it on television, moving quickly to prevent someone else developing the same idea.
