Does anybody know this movie...?

[MaxRock007]

Well, im desperately lokking for a movie i dont know the name of... The only things i can remember are:
1. A crew is trying to do a movie (a B-Movie). The crew casts some girls that could all be Playboy bunny and put them in sexy kinda Army-Uniforms with big guns. A saboteur changes the bullets from fakes into real ones and there is an massacre amongst the actors (very trash-funny indeed)
2. the crew is watching parts of the movie in a drive-in cinema with some space monsters fighting on the screen. One is looking like a big driller and the other one looks like a giant hole. During the fight it looks like they corpulate :-)
3. During a chase near the end of the movie you can see David Carradines Car from "Death Race 2000" and a man in a plastic Godzilla suit running over the street.
Well, thats all i can remember. I should have been released End of 70´s maximum start of the 80´s
Could anybody help we out what movie that is
Thank you so much in advance
