Filmed in England, They Who Dare is undeservedly the least-known of director Lewis Milestones sound films. Set in the Aegean sea during World War II, the film recounts the exploits of Britains Special Boat Squadron. Sent on life-or-death commando missions, the squadron (six English, four Greek) hops from island to island, sabotaging Axis air bases. The centerpiece of the film is an assignment to dynamite German air fields on the island of Rhodes. Robert Westerby is credited with the screenplay of They Who Dare, and Lewis Milestone insisted the story was taken verbatim from the reminiscences of the squadrons two survivors; on the other hand, star Dirk Bogarde claimed that the film was improvised as they went along. …They Who Dare (1954) ( Lewis Milestones They Who Dare )
