Input: Question: How old was Ann Todd when she married David Lean? Passage:The next film directed by Lean was The Passionate Friends (1949), an atypical Lean film, but one which marked his first occasion to work with Claude Rains, who played the husband of a woman (Todd) torn between him and an old flame (Howard). The Passionate Friends was the first of three films to feature the actress Ann Todd, who became his third wife. Madeleine (1950), set in Victorian-era Glasgow is about an 1857 cause célèbre with Todd's lead character accused of murdering a former lover. "Once more", writes film critic David Thomson "Lean settles on the pressing need for propriety, but not before the film has put its characters and the audience through a wringer of contradictory feelings." The last of the films with Todd, The Sound Barrier (1952), has a screenplay by the playwright Terence Rattigan and was the first of his three films for Sir Alexander Korda's London Films. Hobson's Choice (1954), with Charles Laughton in the lead, was based on the play by Harold Brighouse.
