455 years...
So this movie takes place in the year 2455.
The movie never explicitly states the year that the opening scene was supposed to take place in, however Rowan references 2008 when speaking about the history of the cryogenic chambers, and there was some other reference at some point near the beginning that alludes to the fact that the opening scene was the near future (as in sometime around 2015, give or take).
So WHY do they keep saying 455 years? She was NOT frozen for 455 years, unless she was frozen in the year 2000. Even Kay-Em 14 (the robot chick) says "4.55 centuries".
I know this is a cheap slasher-naked-boobs movie with TONS of plot holes, but the 455 years thing is just plain sloppy. When they were filming (presumably in 2000) they must have forgotten that even the beginning scene was supposed to be in the near future. David Cronenberg's cameo at the beginning was the only cool part of this whole mess.
By the way, on the FAQ page, in explaining how Jason's rusty machete could penetrate the reinforced cryochamber door (which appeared to be at least 6 inches thick), someone replied "I guess Jason is just that strong". Come ON. That's like saying someone could be strong enough to throw a cotton ball through a 2 X 4. It has nothing to do with strength. The materials themselves would not act like that, no matter how strong he is. The blade would snap off or bend or something before ever penetrating steel.
Guess the cryochamber was made of aluminum foil.
