Name of cheesy sci fi movie?

In the late 90s I bought a DVD from the $2 bin at Wal-Mart and it ended up being B- gold! The movie took place in a movie theatre in the 50s that was showing a black and white sci fi movie. It was 3 movies in one: the one on the screen in back and white, the people in the audience and an alien invasion of the town of the movie theatre. The people in the audience were hilarious, there was a huge woman ( played by a drag queen) with her tiny husband who followed her around with tons of food, and a cowboy on a date who said the most perverted things to his date, and some others I can't remember. Does anyone know this movie, I can't find the dvd or remember the name! Thx in advance
