The Barbie Movie was a massive success for Mattel. As well as bringing the toy maker a windfall in its share of box office revenue plus intellectual property payments, Greta Gerwig’s film helped keep Barbie dolls relevant for a new generation more than 60 years after they were first produced.

It’s understandable, then, that Mattel’s now rummaging around to see what else it can find to bring to the big screen. There are already Polly Pocket, Hot Wheels and Uno movies in the works. That seemed to leave few assets left to milk, but Mattel’s found another candidate sitting dusty and forgotten at the back of its toy cupboard: the View-Master.
