One of over 700 Paramount Productions, filmed between 1929 and 1949, which were sold to MCA/Universal in 1958 for television distribution, and have been owned and controlled by Universal ever since.
Originally, this film was not supposed to be a sequel to Road to Singapore; in fact, Bing Crosby and Bob Hope were not even supposed to be in it. The film was first offered to Fred MacMurray and George Burns, who both rejected it. While assembling a list of contract Paramount stars to offer it to, someone at the studio remembered that "Road to Singapore" had done relatively well, and Hope and Crosby "seemed to work well together", so it was offered to them. The rest, as they say, is history.
