Three for Bedroom C on AllMovie

An aging movie star and her precocious daughter hide out in the train berth of a scientist during a cross-country journey from New York to LA in this romantic comedy. The whole mess begins when the actress receives an urgent wire demanding that she immediately return to Hollywood to star in a new film. She cares little about the project, but still obeys. Unfortunately, the train is full so she has no choice but to stow away in a sleeping compartment. The berth belongs to an introverted, scholarly biochemistry professor from Harvard who boards in Chicago. Creating more havoc upon the speeding train is the actress's eternally patient agent. As the train chugs westward, romance and comedy ensues. The leading lady, Gloria Swanson, made this farce right after making her classic Sunset Blvd.
