Sky Captain and the World of Tomorrow months before Conran made the movie with his actors, he shot it entirely with stand-ins in Los Angeles and then created the whole movie in animatics so that the actors had an idea of what the film would look like and where to move on the soundstage. To prepare for the film, Conran had his cast watch old movies, such as Lauren Bacall in "To Have and Have Not" (1944) for Paltrow's performance and "The Thin Man" (1934) for the relationship between Nick and Nora that was to be echoed in the one between Joe and Polly. Avnet constantly pushed
Lauren Bacall the 1950s by appearing as the leading lady in a string of films that won favorable reviews. Bacall was cast opposite Gary Cooper in "Bright Leaf" (1950). In the same year, she played a two-faced femme fatale in "Young Man with a Horn" (1950), a jazz musical co-starring Kirk Douglas, Doris Day, and Hoagy Carmichael. During 1951–1952, Bacall co-starred with Bogart in the syndicated action-adventure radio series "Bold Venture". In 1953, she starred in the CinemaScope comedy "How to Marry a Millionaire", a runaway hit among critics and at the box office. Directed by Jean Negulesco and co-starring Marilyn Monroe
