"I promise you, I'm going back to L.A. tomorrow. Monday morning I'll make a call, OK?"

This was actor William Shatner's response to wild cheers from the audience in an appearance at the Salt Lake Comic Conference on Friday. He made this affirmation shortly after posing a question to the same audience if he should appear on 'Big Bang Theory'. "Batman" TV series star Adam West also appeared with Shatner at the comic conference.

According to the Salt Lake Tribune, an independent news source, Shatner and West were asked during the comic con if they would approve to appear as guest stars in another TV series favorite "Big Bang Theory". Shatner's castmates Leonard Nimoy and George Takei had earlier appeared in cameo roles in the show. Also, the main characters in the "Big Bang Theory" idolized science fiction characters like Shatner's Captain Tiberius Kirk.

Shatner is famous for his role as Captain Kirk, Commander of the Federation Starship USS Enterprise in "Star Trek". The Gene Roddenberry-produced television series is a cult classic among science fiction fans. The "Star Trek" franchise has since sired 12 theatrical films, 5 additional television series and memorabilia like books and action figures.

The 'Star Trek' brand is currently owned by Viacom through its subsidiary Paramount Pictures. Its recent 'Star Trek' film, 'Into the Darkness', was the highest-grossing film of the franchise. The film earned over USD228 million in North America and more than USD462 million globally.
