'Frequency' Season Premiere On The CW: How Different Is It From The Original Movie?

The CW's newest time travel series called "Frequency" will premiere on the network on Wednesday, Oct. 5, at 9 p.m. The show, which stars Peyton List, Riley Smith, Devin Kelley and Mekhi Phifer, is a based off a 2000 movie with the same title. But how much of the movie is adapted in the TV show? How different is the "Frequency" TV series?

"Frequency" follows Raimy Sullivan (Peyton List) as a budding New York detective. Her father, Frank (Riley Smith), who was also a cop, died in 1996 and the circumstances surrounding his death has always been tainted. Raimy was just a child when it happened and she hasn't had the chance to really get to know her father.

During a storm, her father's old HAM radio activates and Raimy starts talking with a guy at the other end of the channel on "Frequency." Unbelievably, both learn that they're communicating with each other from different timelines, with Raimy in the present day and Frank settled in the '90s. Thus, the premise of the time travel element.

In the movie version of "Frequency," it is a father and son, played by Dennis Quaid and Jim Caviezel, who establishes a relationship across timelines and airwaves. This relationship is much more complicated in the TV adaptation. "Raimy's father died under suspicious circumstances. He was labeled a traitor and she grew up with this horrible suspicion 'don't turn out like your dad,'" Peyton List said, per the New York Post.

Together, Raimy and Frank attempt to solve what really happened when the elder Sullivan supposedly died in the season premiere of "Frequency." But in doing so, the course of the Sullivan family's history changes, thus affecting Raimy's current life.

Throughout the show, Raimy and her father will also forge a new relationship now that she's an adult, which has never been fully explored in the "Frequency" movie. "You get Frank and Raimy trying to figure out a way to work together when they're people that don't really know each other very well," Peyton List told Den of Geek.
