Although originally wanting to become an actress on the stage, Darnell was featured in a "Gateway to Hollywood" talent search and initially landed a contract at RKO Pictures. There was no certainty, though, and she soon returned to Dallas. When 20th Century-Fox offered her a part, Darnell wanted to accept, but RKO was unwilling to release her. Nevertheless, by age 15 she was signed to a contract at 20th Century-Fox and moved to a small apartment in Hollywood all alone on April 5, 1939. With production beginning in April 1939, she was featured in her first film, "Hotel for Women" (1939), which had newspapers immediately hailing her as the newest star of Hollywood. Loretta Young was originally assigned to play the role, but she demanded a salary which the studio would not give her. Darryl F. Zanuck instead cast Darnell "because he felt that the name would advertise her beauty and suggest a Latin quality that matched her coloring."
