Try a comic book store, or even the comic/magazine section of your local bookseller. Try looking online.
Or, you could make a pair out of some cardboard, a sheet of red transparency and a sheet of blue transparency. Look in the office supply store for clear, blue/red plastic folders. That might work.
hmmm.......
I've never seen a 3-D transfer of the movie on VHS or DVD. The movie was shot and shown in the theater in 3-D.........then was reformatted before it's VHS release, it wasn't in 3-D anymore. The dvd was copied from the VHS transfer so it is not in 3-D either.
If they ever do release a 3-D version of Friday the 13th on home video (or already have and I just havn't heard about it) it will come with it's own pair of 3-D glasses.
If you are thinking that it is a 3-D movie soly because the title of the film includes 3-D, you are mistaken. That is the title of the movie because it was originally shown in the theater in 3-D..........it wasn't released on home video in 3-D. As far as I know, no copies of the movie have ever been released in 3-D...............
If you have a new dvd that they actually formatted to be displayed as 3-D and you didn't get a pair of glasses with it, take it back to the store. All 3-D movies come with 3-D glasses. A 3-D movie is unwatchable without the glasses. All you will see is a bunch of red and blue blurring.
