The Big Bang Theory Season 10 will come in with a lot of excitement, as Christopher Lloyd will guest star. There are no inside details yet on the character, and news on the storyline remains unclear.

According to Variety, the episode "Back to the Future" will air on Thursday, December 1 at 8 pm on CBS. The producers of the CBS TV hit are excited and looking forward to work with Lloyd and are happy with all the episodes where he features. It was hard to get details on episodes from the execs, with many of them saying that they created a fun part fans will surely enjoy.

Rumors say that Lloyd's character will feature in a time-travel sequence, and if this is true, then his role may have to do something with Sheldon. Looking at the previous episodes, Sheldon have always wanted to travel to the future. Fans are of the view that Lloyd could be Sheldon's counterpart, and others are of the opinion that he could be Sheldon's grandfather in a dream sequence as reported by International Business Times.

The focus on this episode will principally be on Sheldon, and the other cast members of "Big Bang" would not have on-camera roles in the spin off. Fears abound that Season 10 might be the last for the sitcom, what with controversies surrounding the fees paid to the show's stars. With negotiations for their contracts ongoing, many fear that back-outs involving stars would introduce the possibility of the show's immediate cancellation.

Nevertheless, many expect the sitcom to undergo a renewal for another season. The issue regarding salaries for the series' high-paid actors may continue to leave "Big Bang's" fate in limbo, but the sitcom's enduring popularity may just prompt the producers to find more ways to keep it rolling.
