Mulder and Scully are about to get pimped out and then some.

Xzibit, the hit-making rapper and hilarious host of MTV's Pimp My Ride, will join Amanda Peet and Scottish comedian Billy Connolly in key supporting roles for the upcoming X-Files movie.

According to the Hollywood Reporter, Xzibit and Peet will play FBI agents working alongside David Duchovny's Fox "Spooky" Mulder and Gillian Anderson's Dana Scully in the second film based on Fox's hugely popular sci-fi series.

No word on Connolly's role. A rep for Fox declined to provide any information on the threesome's characters, and details of the plot remain a closely guarded secret.

What we do know is that unlike the first X-Files feature in 1998, the new film will avoid the series' abstruse mythology and instead work as a standalone installment about some kind of supernatural mystery.

X-Files creator Chris Carter will direct the film from a script he wrote with series writer and executive producer Frank Spotnitz.

Talk of another X-Files movie has been ongoing since the 1998 release grossed more than $189 million worldwide. But the project stalled as Carter and Fox engaged in lengthy litigation over residuals from the show's syndication sales.

The two sides settled earlier this year, clearing the way for the new chapter.

Aside from his seven-season sojourn on Pimp My Ride, Xzibit has guested in CSI: Miami and freestyled opposite Eminem in 8 Mile. More recent film roles include XXX: State of the Union with fellow emcee Ice Cube, Derailed with Clive Owen and Gridiron Gang with Dwayne "The Rock" Johnson.

Xzibit had been set to star opposite Bruce Willis and Woody Harrelson in Pinkville, Oliver Stone's drama about the My Lai Massacre. But that picture was shelved due to the writers' strike, allowing Xzibit to fit the X-Files sequel into his schedule.

Known for her roles in The Whole Nine Yards and NBC's Studio 60 on the Sunset Strip, Peet currently stars opposite John Cusack in the New Line drama Martian Child. She also recently agreed to headline the drama Real Men Cry with Ethan Hawke and Mark Ruffalo.

Connolly had a memorable turn as Uncle Morty in 2004's Lemony Snicket's A Series of Unfortunate Events. Other film credits include White Oleander, The Last Samurai and the voice of McSquizzy in last year's Open Season.

The still-untitled X-Files film is due to begin shooting later this month in Vancouver and hits theaters July 25, 2008.
