Facejacker is a spin-off from the creators of the BAFTA-winning Fonejacker. Kayvan Novak once again plays the man of mystery, but this time he's up close and personal with his subjects rather than on the end of a phone.

Disguised with the aid of prosthetics, Kayvan plays a dazzling multitude of fictional characters, some familiar and some brand new, including: the charismatic and many times divorced car salesman Terry Tibbs; scamster Augustus Kwembe, who hypnotises people to stop smoking but is really eliciting their bank details; and irritating complaint monger Dufrais. All are thrust into real-life situations where they butt up against unsuspecting members of the public.

Brand new faces include charlatan art critic Brian Badonde, and Dr Ali, formerly Saddam Hussein's plastic surgeon of choice.

Facejacker takes Fonejacker to another dimension, showcasing Kayvan Novak's amazing array of voices and characters as well as his sublime comic improvisational skills.

Our Review: This hidden-camera prank show is looking like it is going to be a very strong edition to Channel 4's comedy line-up in April.
