VIDEO: First Look - Kaley Cuoco, William Shatner in New Priceline Super Bowl Ad

Kaley Cuoco, star of CBS's "The Big Bang Theory," will join William Shatner in a new priceline.com (PCLN) ad that will be unveiled during Sunday's pregame show. The ad is the second in a series of spots in which Cuoco plays the daughter of the "Negotiator" character. As the campaign progresses, she shows her hyper-aggressive father how priceline.com's no-bid Express Deals(sm) hotel reservation service is the lighter Touch and highly effective way to score deals on quality hotel rooms. Check out the spot below!

"Sunday's commercials are all about star-studded spots and new looks for brands," said priceline.com's Chief Marketing Officer Brett Keller. "This is the perfect platform to showcase two highly successful celebrities within the same ad. It's not something you see every day."

In the new ad, Cuoco firmly establishes herself as the new, gentler, force to be reckoned with when it comes to saving travelers money on hotel rooms. On her first mission, despite urgings from Shatner to overpower their mark with some heavy-handed tactics ("Use the stun gun! Get the grappling hook!"), Cuoco instead introduces him to Express Deals, a priceline.com service where customers don't have to bid and can get quality hotel rooms with guaranteed amenities like a pool, gym or restaurant at savings of up to 45% over published rates.
