Who Is America? (Channel 4, 10pm)

The arrival of Sacha Baron Cohen's new series Who Is America? last week caught some people on the hop when it became a very late addition to the Channel 4 schedules.

Some viewers may have thought that Baron Cohen coming back to the channel where he first found fame - his character Ali G was the breakout star of The 11 O'Clock Show - was the sort of news that Channel 4 would have been trailing for months.

But then, there is also a strong case to be made for keeping his return to the small screen quiet, both here and in the US, where the series airs on Showtime.

After all, along with the catchphrases, Ali G was most famous for his hilarious interviews with unsuspecting public figures, many of whom seemed so worried about being deemed out of touch that they went along with his line of questioning, no matter how outlandish it may have been.

But the more famous you become, the harder that trick is to pull off. Luckily, Sacha had other characters to draw on, including Borat, the Kazakh journalist who became the star of his own smash-hit, Oscar-nominated film which saw him travelling around America.

Sacha then unleashed the Austrian reporter Bruno on what seemed to be increasingly less unsuspecting public.

Some fans may have wondered if it was Sacha's increasing fame that led him to move into more conventional film stardom - as well as appearing in the comedies The Dictator and Grimsby, which he co-wrote and produced, he also cropped up in the Madagascar movies and Hugo. He even got to show off his musical chops in Sweeney Todd: The Demon Barber of Fleet Street and Les Miserables, making it more of a shame that his plans to play Freddie Mercury never came to pass.

But maybe the actor and comedian was also just biding his time and lulling politicians into a false sense of security, because we now know that he's spent the past year undercover, speaking to people from across America's cultural and political spectrum.

And we knew he'd bagged some big names before the first episode had even aired, as a couple of them took to social media to register their displeasure.

Sarah Palin claimed she'd been 'duped' into taking part in an interview, saying: "Ya' got me, Sacha. Feel better now? I join a long list of American public personalities who have fallen victim to the evil, exploitive, sick 'humour' of the British 'comedian.'"

However, according to David Nevins, President and CEO of Showtime Networks Inc, it's not just about tricking famous faces. He says: "[Sacha] is the premier provocateur of our time, but not for the sake of 'gotcha' moments. Behind the elaborate setup is a genuine quest for the truth about people, places and politics. Nobody knows how to cause a stir like Sacha Baron Cohen..."

And given the reactions so far, expect this second episode to get people talking...
