Ali Baba Bujang Lapok (English: Ali Baba the Old Bachelor) is a 1961 Singaporean Malay-language black-and-white comedy film directed by, written by and starring Malaysian silver-screen legend P. Ramlee and produced in Singapore by Malay Film Productions Ltd. Based loosely on the story of Ali Baba from 1001 Arabian Nights, the film is occasionally self-referential and contains elements of anarchic comedy, burlesque comedy, satire and farce.

When Norsiah comes to ask for flour for the umpteenth time, Kassim Baba loses his temper and lashes out at her sending her home in tears.

Marjina discover the hidden thieves and, with the help of Ali Baba's wife and widowed sister-in-law, pour boiling oil into all the individual jars.

Although Ali Baba Bujang Lapok is filmed as a period piece set in an unidentified country with a Middle-Eastern look (though it might be Iraq, Baghdad), it is filled with deliberate anachronisms which are used for humour.

When on leave, the 40 thieves also dress as various anachronistic characters, among them a cowboy, wig-wearing judge and a World War 2-era Japanese soldier.

In addition, the 40 thieves seem to function as a proper business, offering members health benefits, performance-based bonuses and overtime pay.

It is shown in a scene where Marjina is buying some belacan at the city market, where the seller claims that selling cannabis and opium is legal but belacan is illegal, as it is smuggled from Malaya, even though the actual legal status for those three items in Malaya is the opposite and the words ganja and candu were muted out by shrimp paste smuggler.
