Great Scott! 1.21 jigowatts! Additional exclamations! We may not keep up with FOX's thriving family comedy 'Raising Hope' all that often, but when 'Back to the Future' gets thrown into the mix, you can bet we're gonna see some serious sh*t. Not only that, but it seems Doc Brown himself Christopher Lloyd will guest star on the episode to get in on the fun! But where (or when) could 'Raising Hope' go with a 'Back to the Future' episode, and who could Lloyd play if not himself?
