The toys are taking over the big screen.

The latest classic toy getting its own movie is the View-Master, the stereoscopic eye device. Mattel is teaming up with MGM to develop the project. No writer or director is attached yet.

Mattel Films, which was launched last year, has been busy making deals with Hollywood studios. It is also working on a Hot Wheels movie and a Barbie flick starring Margot Robbie.

And earlier this month, Mattel and MGM announced they are partnering on an American Girl movie.

View-Master was launched at 1939 New York World’s Fair, bringing 3D images of tourist attractions to the masses. It exploded in popularity in the 1950s thanks to a licensing deal with Disney. The toy came under the control of Mattel in 1997.

Recently, Mattel introduced the updated View-Master VR, a virtual reality product that features what the toymaker calls “a whole new level of realism."
