'Big Bang Theory' Season 8 Release Date, Spoilers, Cast News & Penny New Role (VIDEO)

"The Big Bang Theory" Season 8 news is heating up a few months away from the Fall premiere. The show co-creator and executive producer Chuck Lorreat spoke at the Television Critics Association's summer press tour and shared some interesting spoilers and plot news for Season 8.

"Penny (Kaley Cuoco) has an interesting arc this year where she puts acting down," Lorreat said. "She gets a shot to be a pharmaceutical rep at Bernadette's [Melissa Rauch] company."

With the new job and independence, there could be some friction with her husband-to-be, Leonard (Johnny Galecki). "She's going to start making some money, which will unbalance their relationship as the power shifts," shared Lorre of the Season 8 storyline. "She's going to find some confidence and self-esteem, which acting does not provide in great heaping doses."

"These characters, as they grow, they deal with more things. Sheldon [Jim Parsons] has grown unbelievably over seven years from where we began. We could never have imagined the stories we've been doing in the past year or so six years ago," he said.

The hit CBS show was renewed for an eighth season on February 2014 and also announced that the first portion of the new season would air on a different night due to Thursday Night NFL Football. Then in March, CBS added three more years past Season 8, confirming the show will make new episodes through 2016-17. "The Big Bang Theory" will start airing on Mondays on CBS, premiering Season 8 on September 22, 2014 before "Mom" due to the NFL game schedule. The show will then move back to Thursdays on October 30, 2014 and air before "The Millers" for the remainder of the season.

A huge cast out of the surprise bag for "The Big Bang Theory" was that "Friends" star Lisa Kudrow will reportedly be making cameos this season as Penny's mom. Penny's mother has been come up several times in the show, but she has never been seen. With Penny getting married, it would be a good time to reveal Penny's mom, which is expected to be Kudrow. Fans seem excited about a Kudrow appearance and think she will fit in good with the corky chemistry of the show.

Cast star, Cuoco-Sweeting shares her excitement about Kudrow joining the crew for Season 8 sharing, "I don't know what they're going to do, but I have always thought - and I hope this doesn't offend her (Lisa Kudrow) because I know she's super young, though we know Penny's mom got knocked up very early, - that Lisa Kudrow would be so perfect. I've said that for years. I think it would be hilarious, plus I'm a huge fan of hers, so it's a selfish wish."

The big wedding with Penny and Leonard is another exciting storyline that fans are excited to see play out in season 8. Cuoco-Sweeting talked to TVLine shared her excitement for Penny's marriage to Leonard in the upcoming season saying, "If I could write it myself, I think Leonard will be more of the bride, because I think it would be funny if he were the planner. Penny is so aloof, she'd be a lot more easy-going than Leonard."
