Badly hung over from mixing radish juice and carrot juice the night before, bugs staggers up his stairs and accidentally into a space rocket that has been established as a launch point directly above his home. When the rocket reaches his destination, Bugs stumbles into a plot by an alien to destroy the earth - a plot Bugs has no option but to try and foil.
This film is one of the many that started to cash in on the whole sci-fi scene and saw the creation of the alien character who has faced up to several of the usual characters. The plot here is too simple for my tastes and doesn't create that many funny sequences. The overly silly setup is happily put aside as soon as it can be to create a battle of wits between Bugs and alien. Sadly this chase is full of daft looking monsters who are easily outwitted by Bugs - but only in one amusing sequence. Before you know it the film is finished (and with a whimper at that).
Bugs is good and the alien is funny if you like him; the problem seems to be with the material, which is uninspired and lacking in real imagination or spark. Bits of it are still pretty amusing but mostly I found it to be quite lacklustre considering the characters involved. Overall, it is worth seeing because all Bugs Bunny films are, but it would have been nice if the material had ran to a few more sequences with more laughs.
