The rumors of "The Big Bang Theory" to end after season 10 has been swirling for quite awhile now. Although the cast and staff have not released any statement regarding this issue, "The Big Bang Theory" lead cast contracts are going to expire soon which added more fuel to the fire.
"The Big Bang Theory" Season 10 lead actors, Kaley Cuoco (Penny), Jim Parsons (Sheldon Cooper), and Johnny Galecki (Leonard Hofstadter) signed a new three-year contract in 2014 to continue their "The Big Bang Theory" characters.
If this is the case, then their contract will expire in 2017 which will only allow them to portray their roles until "The Big Bang Theory" Season 10.
Basing on their contracts, the rumors of "The Big Bang Theory" season 10 being its last might actually be true, unless Kaley Cuoco, Jim Parson, and Johnny Galecki will renew their contracts for three or more years.
Since nothing was reported yet regarding these "The Big Bang Theory" lead actors signing another contract, it is understandable that "The Big Bang Theory" is plagued with rumors of cancellation.
In an interview with Variety, "The Big Bang Theory" creator Chuck Lorre revealed that he prefers having live audiences while filming because he likes an instant feedback.
The live audience will help Chuck Lorre know which jokes are funny enough to make it on air, and which lines didn't get enough reaction.
"There's a terrific vulnerability when you're working in front of a live audience," "The Big Bang Theory" creator said. "There are no tricks involved. There's no editing or post-production magic. It's very vulnerable. And I would guess that vulnerability is part of the appeal. When it truly works, it's great."
