Os Trapalhões na Guerra dos Planetas (lit: The Bunglers in the War of the Planets) is a 1978 Brazilian comedy film directed by Adriano Stuart.

It is the thirteenth film of the Brazilian comedy group Os Trapalhões, starring Renato Aragão, Manfried Sant'Anna, Antonio Carlos Gomes, and Mauro Gonçalves.

Outside of Brazil, mainly in English-speaking countries, this film is known by the suggestive title of Brazilian Star Wars.

It features characters resembling Luke Skywalker, Princess Leia, Darth Vader, Chewbacca, and Stormtroopers.

Because of the special effects, the film was shot in videotape format, but was later expanded to 35mm in the United States, although there are legal restrictions on showing the material outside Brazil.
