"He's just got a really clear vision of what he wants." The love-in is certainly mutual; Morris has openly praised Kayvan's "massive balls".

"Let's hope he means my courage," deadpans the actor.

Novak was the handsome, actorly man hiding behind the bobble-hat balaclava and skilfully impersonating everyone from a camp African scamster to an absurdly meek Indian call centre drone in phone calls to bamboozled members of the public.

The new series features wide boy Terry Tibbs making false claims about fitness equipment as a guest in the perma-grinning Price Drop TV studio, Brian Sewell-spoofing art ignoramus Brian Badonde tormenting a gallery owner with his surreal clucking and all-new African trickster Dr Augustus Kwembe attempting to extract a man's bank details using half-arsed hypnosis.

He's clearly got a clanging pair of comedy cojones. "A lot of the characters are quite lovable," reasons Novak.

"It's really just about these four blokes who try to plan something and fuck it up." Controversy is something he's had experience of.

Before the first series of Fonejacker, Channel 4 fretted heartily about the possible bulging postbag of complaints it would receive because of Kayvan's ethnic accents.

"I think [being Iranian] let me get away with it more," he reasons.

"If there were four white dudes called the Fonejackers, who each did a different race's accent there might be a bit of …[adopts Indian call centre accent] politically incorrectings." He seems to take any uproar caused by his comedy in his stride.

Whether it's Jeremy Beadle wearing a joke shop beard, Dom Joly barking into a jumbo-sized mobile phone or Rio Ferdinand "merking" a baffled celeb bezzie, the whiff of whoopee cushion-clutching staleness is hard to escape. "I think a lot of pranking on TV can be quite lazy," explains the 31-year-old British Iranian actor in his sleepy London drawl. ' My comedy is more character-driven so I certainly wouldn't say I'm the 21st-century Beadle." So far, this approach has served him well.

After a career as a jobbing actor brought the obligatory roles in Spooks, Holby City and glum George Clooney thriller Syriana ("I played a lot of pimps, villains and evil Turks called Mustapha," laughs Kayvan adopting a tache-twirling baddie voice), he finally won fame and the 2008 Best Comedy Bafta for E4's Fonejacker.

Now he's decided to give Channel 4's phone bill a breather and take those characters and others out into the open for his new series, Facejacker.
