IDW is going where they don't need roads.

In a press release that is apparently from the future, the publisher announced Wednesday it'll be publishing a new Back to the Future anthology comic starting in October. Subtitled Untold Tales and Alternate Timelines, the series will follow alternate versions of events from the movies, fill in the gaps between them, and offer up prequel stories. (Maybe we'll see Doc Brown's college years!)

Here's the big news: Bob Gale, the co-writer of all three movies, will be one of three writers working on the new series. He explained the focus of the series in the press release:

We’ve subtitled this ‘Untold Tales and Alternate Timelines’ because for years, fans have asked questions about things that happened before the events of the trilogy, in between the events of the trilogy, or in our alternate realities. In this series, we’ll finally answer some of those questions, with our focus squarely on the characters everyone loves.

The series' other two writers will be John Barber (Transformers vs. G.I. Joe) and Erik Burnham (Ghostbusters), with art duties split between Brent Schoonover (Batman ’66) and Dan Schoening (Ghostbusters).
Here's what the release says about what's to come in issue #1:
In the first tale of the debut issue, we head back to 1982 and witness the very first meeting between Marty McFly and Doc Brown, before their incredible adventures together began. Then in the second chapter, we head back even farther to 1943 and see how Doc Brown got himself mixed up in the infamous Manhattan Project! This first issue will feature three standard covers, by Schoening, Schoonover, and Amy Mebberson (My Little Pony). Additionally, Back to the Future #1 will join in on the fun of Artist’s Edition Month in October with an original art styled cover by Schoening!
So hey, I wasn't too far off on that Doc-Brown-college-years thing. Let me see if I can predict another one: Biff as a baby! Baby Biff! Let's make it happen, IDW.
