Bad Taste Peter Jackson’s first flick. WAY over the top SF/horror. Total cost =about US$5,000 over 4 years.
El Mariachi This is much better than the bigger budget remake, Desperado, although I admit I’ll watch Salma Hayek in damn near anything.
Killer Klowns From Outer Space Great fun.
Bubba Ho-Tep Come on, who doesn’t want to see Bruce Campbell as a drug-addled Elvis fighting a soul-sucking zombie with the help of Jack Kennedy (as played by Ossie Davis)?
Toxic Avenger GO Team Troma!
I like low budget movies, so I could come up with a pretty extensive list, but then there would be less for others to post. But there’s five off the top of my head.
