The process of finding references is highly annoying. So in Rinzler's "The Making of Star Wars" book, page 303. There are mentions of several films which fall under the banner which might have a reference:
<blockquote>The inevitable slate of imitations was quickly planned by other studios as well. Walt Disney productions began work on two films: Space Station One <edit> and The Cat from Outer Space.<blockquote>
Now I too enjoy pointing out Disney's continuous copying of everything and then contradictory response to other's creativity. But i've just sat through 'The Cat from Outer Space' (http://www.imdb.com/title/tt0077305/) and I find it absolutely astounding that they would bother to mention this film at all. Sure there's a dogfight sequence at the end, and a space ship in the beginning, but to spend time to put this in the definitive book on Star Wars's history, it's laughable.
Here's the things which stuck out in my mind as possible references.
(characters look at the space ship dialog) "There she is" 31:50 (similar to ANH, Han in DS)
(ANH like dogfight between airplane and helicopter dialog) "Turn this thing around." "Hold on." "Here they come." "They're still on our tail." 1:32:00 The first is close to Ben but for the most part they're generic.
But this movie came out in 1978, but there's a bunch of things which sound similar to:
"The scoundrel." 54:00 ok that's just one word, but you've got to pick up verbage from somewhere.
"Why aren't they doing something" (sorta like RotJ where the Empire's fleet is waiting for the Emperors signal before attacking the rebel fleet.) again weak.
"It's a Trap!" 1:28:20 Could this be one of the inspirational clues for Ackbar's famous tirade?!
Anyway it's a conundrum why 'The Cat from Outer Space' is mentioned in the Making of Star Wars book. There seem to be more questionable inspirations then references.
...Luckily for every one of these questionable references, there are some definitive ones. Like Toxic Avenger 4 : Citizen Toxie, where the ending has Toxie (with a mop) fighting i guess his clone who's got a double ended mop, and while they're fighting (a la TPM) two in utero twins are mimicing their moves in their own fight. Now that's a quality Star Wars Reference.
