"Mythbusters" new season comes with a different vibe, and as expected, a smaller cast. The show will also go back to its educational format.

Fans of the show have new things to look forward to when "Mythbusters" new season comes in 2015. Show-runner Dan Tapster describes a "new look, a new vibe, and it's become more educational again" in the next run. There's also a smaller cast to expect, which may or may not be a good thing.

Discovery Channel previously confirmed three of the show's mainstays aren't coming back next season; Grant Imahara, Kari Byron and Tory Belleci are out due to unsettled salary negotiations, according to a report.

Tapster commented in an Entertainment Weekly interview: "We were very keen for [Imahara, Byron and Belleci] to be a part of the show, we are massive fans of theirs, and what they did over 10 years was phenomenal.

There were negotiations, and based on those negotiations, they opted out. It's a shame for them. It's a shame for us. But it gave us the opportunity to reinvent the show, which it kind of needed."

Though the series will push through with a smaller crew, Savage and Hyneman have their work cut out for them, doubling effort in producing "Mythbusters" new episodes.

"One of the biggest changes of Kari, Grant, and Tory's departure is that Jamie and I now have to produce all 42-and-a-half minutes of the episode, but we don't have twice as much time to shoot it. That means the mental work for the show doubled. Every sequence transition has to be really tight."

The "Mythbusters" new season should offer interesting propositions for TV show fans. The duo will prove or disprove myths in TV shows, including the classic prank of dropping a cherry bomb into a toilet bowl a la "The Simpsons" and recreating the machine-gun finale of "Breaking Bad," if Walter White's idea would actually work (cnet.com).
