YES you have to wear 3d glasses for 3D movies
Monster vs Aliens 3D
It's basically the same thing. I mean they are both 3D. The only real difference is that Imax 3D is made with Imax cameras.
Some one-reelers were made in 1915. The first full length 3D film was "Power of Love" (1922). It starred Elliot Sparling, Barbara Bedford.
Yes. I have watched two 3D movies, and both times they sold 3D glasses there for only one dollar each.
