Christopher Lloyd is a man who’ll jump at any chance to don a Hawaiian shirt, stand in front of a wind machine and shout “Great Scott!” A new LEGO Dimensions trailer is as good a reason as any.

Good old Doc Brown is getting his own Fun Pack when LEGO Dimensions launches this September, adding $9.99 or so to the large amount of cash LEGO fans need to stockpile for the September release. He’ll join Back to the Future’s Marty McFly as well as characters from Scooby Doo, DC Comics, Portal, Doctor Who, Jurassic World, The Simpsons, The LEGO Movie, Ninjago, Chima, Lord of the Rings and whatever other properties WB and LEGO can scrounge up for their toys-meets-games jam.

Where we’re going we’ll just need our wallets.
