Earlier this week we learned that IDW Publishing has obtained the rights to publish comics based on the popular time-travel movie trilogy Back to the Future. Screenwriter Bob Gale, along with John Barber, Erik Burnham and a "rotating cast of artists," will bring the adventures of Marty McFly and Doc Brown to the printed page.

While the announcement on Wednesday mentioned "Batman '66" artist Brent Schoonover and "Ghostbusters" penciller Dan Schoening are working on the project, it looks like that rotating cast of artists included Secret Identities artist Ilias Kyriazis at one point.

In a post on his blog, the artist shared some concept artwork for both Marty McFly and Doc Brown, noting that he had to stop working on it to make room for another IDW project.

"I had to put on pause my involvement with the project though so I could do Dirk Gently," Kyriazis wrote on his blog. "We'll see if I end up doing more BttF stuff in the future."

You can check out one of his pieces below, and the rest on his blog.
