The main premise of the film (both its plot and characters) is mostly influenced by George Lucas’s sci-fi trilogy “Star Wars,” but Brooks borrows from the likes of nearly every popular sci-fi franchise, including “Star Trek,” “Aliens,” “Planet of the Apes,” and even the not-so-science-fiction tale “The Wizard of Oz.” Brooks includes a good collection of quality gags throughout, but it’s Moranis’ crowd-pleasing re-creation of Darth Vader that ultimately wins in the film’s internal battle for absolute absurdity.
A pr�cis of the film's plot is not necessary: Suffice it to say that there are a passel of jokes -- one coming roughly every 20 seconds -- made at the expense of "Alien," the "Star Trek" movies and the "Star Wars" films, with the latter taking the brunt of the attack.
Then rewind a little to Brooks' Spaceballs, and see how all the signs were there: the strained humor, the lame Star Trek references, the downright painful puns.
In addition to Star Wars, Brooks and company take potshots at Star Trek, Transformers (as in Howard Korder's 1985 off-Broadway space spoof "Episode 26," there's a kind of "Heavenly Hoover" involved in the climax), Alien, Max Headroom, and The Wizard of Oz.
