What other adventures could have taken place within the world that Christopher Lloyd's legendary character painted as he told Michael J. Fox's Marty that he and his family had already been back to the new future they helped create? More importantly, how did the eccentric Doc get used to family life, just as he was starting to get used to being in love? You can see where this line of thinking inspires a multitude of questions, and it won't be much longer until Back to the Future: Tales from the Time Train answers them for comic and movie fans waiting in the lurch. The first issue of this new series will be up for sale on December 27th.
