Question: Who appeared with Alan Napier in the film that was released in 1943? Passage:He made his American stage debut as the romantic lead opposite Gladys George in Lady in Waiting. Though his film career had begun in Britain in the 1930s, he had very little success before the cameras until he joined the British expatriate community in Hollywood in 1941. There he spent time with such people as James Whale, a fellow ex-Oxford Player. He appeared in such films as Random Harvest (1942), Cat People (1942), and The Uninvited (1944). In The Song of Bernadette (1943), he played the ethically questionable psychiatrist who is hired to declare Bernadette mentally ill. He also played the vicious Earl of Warwick in Joan of Arc (1948). He performed in two Shakespearean films: the Orson Welles Macbeth (1948), in which he played a priest that Welles added to the story, who spoke lines originally uttered by other characters, and MGM's Julius Caesar (1953), as Cicero. He appeared as Mr. Rutland in the Hitchcock movie Marnie (1964).

Question: Which film directed by Lean did better at the box office - the film released in 1949, or the film released in 1950? 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.
