'Big Bang Theory' Cast Reveals What They Know About the Season 11 Premiere

Several cast members of The Big Bang Theory dropped by San Diego Comic-Con to discuss a variety of topics with fans, including what they know about the upcoming season 11 premiere.

While Kaley Cuoco, Johnny Galecki, Kevin Sussman and Kunal Nayyar were present at the panel, only Galecki and Nayyar dished on what they've seen of the episode's script.

When asked what they wanted to happen to their characters in season 11, they revealed that they have no idea what the writers have set up for Leonard and the rest of the BBT crew.

"I have trust in the writers," Galecki said. "Things are going so well, so they have it in their head. Who am I to change it?"

"We don't get the script until Tuesday before we shoot on Wednesday," Nayyar said. "So it is like Christmas Eve and Christmas morning, when we get to see it and then go shoot it. We trust the writers completely."

This strategy is not to be unexpected with a series as beloved as Big Bang. Other shows, such as Orange is the New Black, leave their cast in the dark until it's time to film.

The most recent season, season 10, ended its finale with a huge cliffhanger.

Sheldon (Jim Parsons) rushed to his girlfriend Amy's (Mayim Bialik) apartment to propose. He pops the question just as the show ends, leaving fans anticipating an answer.

The Big Bang Theory will return to CBS on Monday, September 25 at 8 p.m.

'Big Bang Theory' Cast Reveals Their Special Guest Fanboy Moments

The cast of The Big Bang Theory is getting ready to return to CBS for two more seasons, but first they dropped by San Diego Comic-Con to discuss a wide variety of topics with fans.

One of those questions was, "What guest star gave you a fanboy moment?" and the answers did not disappoint.

Some were simple favorites, like Johnny Galecki's choice of Bob Newhart. The comedy legend has appeared on the sitcom four times in recent seasons, playing a former TV scientist named "Professor Proton."

Kevin Sussman took a geekier approach to his picks, which were Star Trek: The Next Generation star Wil Wheaton and the late Batman actor Adam West.

"When I first came on the show, I met Will Wheaton, who I was a huge fan of," Sussman said. "So I tried to play it off, but within minutes of meeting him he was teaching me card games. And then years later when Adam West was on set, Will Wheaton the whole time, was talking about how it was to be in the same room with Adam West. Then I got to see him go over and do the thing I did to him, 'Oh, Mr. West....'"

Kunal Nayyar lived out his own fantasy when Wonder Years' Danica McKeller guest starred on the season three, episode "The Psychic Vortex."

"I got to make out with Danica McKeller from Wonder Years," he said. "And when I was in New Dehli I had been nervous about my first kiss and so then I thought about it just like Kevin and Whinney, and so then in real life, well real Big Bang life, I got to kiss her. And then she was pregnant nine months later. Just facts."

The Big Bang Theory will return to CBS on Monday, September 25 at 8 p.m.

Having been together for over ten years, this cast is understandably close-knit. As you can imagine, they got a bit teary-eyed when the proposal took place.

"I take polaroids of all the magic moments on the set," said star Kaley Cuoco. "So we were all behind the camera before the scene, and I started crying when it happened, even though I knew it was going to happen."

Cuoco wasn't the only one who got choked up. Her co-star Kunal Nayyar chimed in to say that he had a hard time keeping his composure.

Kaley Cuoco Is Keeping This One 'Big Bang Theory' Secret to Herself

Whether big or small, every TV show has its own set of mysteries. The Big Bang Theory is no exception.

For 11 years now, fans of the long-running CBS sitcom have labored over one detail that has never been released.

"What is Penny's last name?!"

With the exception of Penny, every character on the show has always had a first and last name. For whatever reason, Penny never did.

Now, having married Leonard, the character does carry the last name of Hofstadter, but that doesn't stop fans from wondering what her maiden name is.

During the Big Bang panel at this year's San Diego Comic-Con, the floor was open to questions from fans. One of these fans asked Kaley Cuoco if she knew Penny's maiden name.

"In my head, I have one, but now I am Hofstadter. So it is like Cher at this point. So, Im not telling."

While Penny was never given an official last name by the writers, Cuoco came up with one on her own. This isn't exactly uncommon for actors, especially those who have had certain roles for an extended period of time. Many performers will give their characters backstories and fill in details that may have been left out by the creative team.

So, Penny does have a last name, but it doesn't look like Kaley Cuoco is going to spill the beans any time soon.
