They are (apparently in no particular order):
- Barbarella (Roger Vadim, 1968)
- Piranha 3DD (John Gulager, 2012)
- Alien vs. Predator: Requiem (The Brothers Strause, 2007)
- Highlander II: The Quickening (Russell Mulcahy, 1991)
- Roller Blade (Donald G. Jackson, 1986)
- 2012 (Roland Emmerich, 2009)
- Superbabies: Baby Geniuses 2 (Bob Clark, 2004)
- Mac and Me (Stewart Raffill, 1988)
- Battlefield Earth (Roger Christian, 2000)
- After Earth (M Night Shyamalan, 2013)
Barbarella is freaking awesome and I’ll fight over that.
It is, however, bad sci-fi. Great movie, just not really sci-fi in the important ways.
