The Hollywood Reporter:

MGM and Mattel are partnering up to develop a live-action feature film based on the toy entertainment company’s classic View-Master toy line.

Mattel Films, the feature arm launched late last year by the El Segundo-based toymaker, and MGM will co-produce the film. Robbie Brenner, Mattel’s head of film, and Cassidy Lange, MGM’s co-president of production, will oversee development.

No writer or filmmaker is attached.

I don't even know what the idea is here.
