It's called Os Trapalhões na Guerra Dos Planetas (The Tramps in the Planet War, 1978) and it's quite clearly a rip-off of Star Wars, in which four Earth tramps are recruited by Prince Flik (Luke Skywalker) to utilise "their expert help in retrieving half of the “brain computer" back on his home planet.
I discovered this through a review at The Wave Magazine's site (after typing 'tiki drum' into Google, would you believe?) The review alone is a good laugh and well worth reading:
"There’s a slight language barrier since the movie is in Portuguese, which I do not speak, and the subtitles are in English, which the person doing the subtitling does not speak."
"For added drama, the film switches to super-slow motion every time one of them does a spectacular move like kicking clumsily or shoving someone into the sand. This technique is so overused that the fight drags out longer than the spastic disco song they use for background music and the last few minutes of the fight take place in silence."
"While they search for Zuco, they run into random dangers like invisible men, flying fruit, a giant tarantula and a baby birdman. Each problem is solved in the same way – panicking, then going in the opposite direction of the menace."
I suspect, however, that the reviewer didn't even bother trying to be funny. The film seems bizarre enough. Kind of like Kung Pow, although of course, Kung Pow was meant to be bizarre and pointless. I also suspect that, as with Kung Pow, I'll be several thousand braincells poorer by the time the end credits roll. As would anyone else within a 500 meter radius.
