Ankle Biters........a low budget horror movie about midget vampires. It was hilarious. Don't know how much it cost to film, but I'm sure it was extremely low.
If today were opposite day, you would win the thread in a landslide. There's not a better example of sh***y movie that cost a gazillion dollars in the world.
I dont know what the budget was, but shoot em up was a TERRIBLY BAD movie EDIT: budget = $40 million. still terrible.
