This film has been referred to numerous times as "the worst of Abbott and Costello". I haven't seen that many A & C pictures so far, but from those that I HAVE seen I'd say "Comin' Round the Mountain" and "Lost in Alaska" and maybe even "Meet the Keystone Kops" are worse than this one, therefore the above statement cannot be true. The best thing about "Go to Mars" are the special effects, which are creative and at times even ingenious; before you complain about them from a "modern" perspective, consider that they are about on the same level with those of, say, "Superman IV" - and that was made 34 years later! Unfortunately, much like "Meet the Keystone Kops", this film gives you the impression that more time was spent on the technical tricks and effects than on providing enough funny material and routines for Abbott and Costello. The funniest exchange in the movie comes early on: Dr. Orvilla: "Why did you tell them that you are Dr. Orvilla?" Lou: "I didn't tell them, THEY told ME!". And although the absence of songs is welcome, the two escaped convicts who eventually join A & C in their trip to Venus get too much screen time on their own. (**)
