Great Scott! We're only nine days away from October 21st, 2015, the date Back to the Future fans have been waiting for since the second movie hit theaters back in 1989. And since Halloween also conveniently happens to take place this month, it's a great time for this infographic from HalloweenCostumes that lists all of the costumes worn by Marty McFly, Doc Brown, and Biff Tannen throughout the time-traveling trilogy.

A small correction, though: in the section of Doc costumes from Back to the Future Part III, the first picture they have claims Doc wore a yellow shirt and hat in 1985. But that took place in 1955, as Doc helped Marty prepare to head back to the Old West. Hey, I get it: time travel can be confusing. Which BTTF costume is your favorite?
