Variety:

Tom Hanks is headed back to outer space.

The Oscar winner is set to star in a feature film based on a Mattel action figure from the 1960s called Major Matt Mason, numerous insiders familiar with the project tell Variety. The film is set up at Paramount Pictures.

I’ve been hearing rumors about a Major Matt Mason movie since the ’90’s, when it had been 30-goddamned-years since the action figures were out.

…who is this for, exactly?
