Former "Psych" cast members James Roday, Maggie Lawson, Kirsten Nelson and Corbin Bernsen reunited at New York Comic Con on Saturday.

The stars -- and the show's creator Steve Franks and executive producer Chris Henze -- talked about the series' eight seasons on USA Network, as well as promoted "Psych: The Movie" and revealed recurring guest star John Cena will also return for the one-off TV project.

Cast member Dule Hill appeared via video and announced the film's premiere date will be Dec. 7.

"Fake psychic detective Shawn Spencer and Burton 'Gus' Guster open up their new office in San Francisco, appropriately [though perhaps awkwardly] named psychphrancisco, and are back in business solving a case after a mystery assailant targets one of their own," a synopsis for the TV movie said.

"A comedic thrill ride follows, as the wild and unpredictable Psych team pursues the bad guys, justice ... and food!" .

The show initially ran on the cable network 2006-14.
