The Road to Singapore is the first of the "Road To" movies that teamed up Bing Crosby, Bob Hope and Dorothy Lamour. Interestingly, in this film Lamour gets a higher billing than Hope, but their positions are reversed in subsequent films.
They do a moonlight flit by boat, Crosby to escape responsibilities and marriage, and Hope to escape an irate father. Their money runs out and they end up on a tropical island en-route to Singapore. They team up with Lamour, a poorly treated performer who they save from the clutches of her brutal dancing partner, played by a young Anthony Quinn. Initially she is their unpaid cook/housekeeper but inevitably a romantic triangle develops. Several routines revolve around their unsuccessful attempts as conmen trying to sell remedies and cleaning fluids. They also almost get married off to local girls at a rather un-PC native feast where there is plenty of blacking up and wild dancing. Eventually, responsibilities, in the form of Crosby's father and his fiancée catch up with them and the various relationships are resolved.
In the meantime, there is plenty of fast patter, in-jokes, songs and dance routines. Even the patacake, patacake routine is first seen here. This is not their strongest film but it flowed along at a reasonable pace. There was a chemistry between the three stars and the dialogue and jokes between Crosby and Hope were typically brisk.
