Here's the first in a series of behind-the-scenes videos going behind the scenes of Telltale Games' Back to the Future spin-offs. This one introduces the basic backstory – there's a game, Bob Gale is involved – and show us Christopher Lloyd recording some of his dialogue and talking about the gig.
Best of all, however, you'll also get to see some work-in-progress animation of the Doc speaking to Marty. I'm hoping they've tightened the lip-sync up somewhat in the meantime.
Should any more in this series of videos show anything of particular interest, I'll be sure to post them here too.
