The Big Bang Theory's massive success has allowed for a huge budget that's bankrolled some amazing guest stars, and it sounds like they're about to add Back to the Future's Doc Brown to that list. That's right, Christopher Lloyd will soon be taking his turn filling a guest spot on the Dec. 1 episode of the CBS series.
"We're so excited to be working with Christopher Lloyd and think we've created a fun part that fans will really enjoy," the show's executive producers said in a statement on Wednesday, via Fox News.
The executive producers' statement is pretty vague, so of course our minds are running wild with the possibilities of what a Lloyd guest-starring spot will look like. TBBT has been killing it with the family member casting lately (hello, Katey Sagal as Penny's mom and Jack McBrayer as her brother? Genius), so it would be fun to see Lloyd turn up as Sheldon's role model uncle.
We also know that Lloyd has the role of a wacky scientist down pat, so him subbing in as a professor at the university where the guys work isn't out of the question either.
Then again, it wouldn't be surprising if Lloyd showed up as Doc Brown himself in one of the guys' epic dream sequences — talking about theoretical physics and offering them an epic time travel adventure. And a cameo is not outside the realm of possibility, considering LeVar Burton, Steve Wozniak, Stan Lee, George Takei, James Earl Jones, Carrie Fisher, Stephen Hawking and of course, Wil Wheaton have all played themselves on the show.
