In 1940, Lamour made her first "Road series" comedy film "Road to Singapore". The "Road series" films were popular during the 1940s. The sixth film in the series, "Road to Bali", was released in 1952. By this time, Lamour's screen career began to wane, and she focused on stage and television work. In 1961, Crosby and Hope teamed for "The Road to Hong Kong", but actress Joan Collins was cast as the female lead. Lamour made a brief appearance and sang a song near the end of that film.
