The first major inkling of the project (which isn't even listed on his IMDB page yet) came at the end of June, when Showtime released a very mysterious teaser for the show, asking: "So how do we promote perhaps the most unsafe show in the history of television when we're not allowed to show it?"
The teaser's tagline may hold the answer: "Imagine if Sacha Baron Cohen had been undercover secretly filming a show for a year?"
Cheney was asked by a thickly-accented voice off-camera: 'Is it possible to sign my waterboard kit?' This is gonna be a good 'un.
Who Is America? is set to premiere in the States on Sunday 15 July, with no set release date for this side of the Atlantic just yet.
Cohen's new character and conceit for the show is being kept under wraps for now, but we can't wait to see what he's been up to.
On July 4th, the British comedian and actor Sacha Baron Cohen revived his long-dormant presence on Twitter to post an odd video edit of President Donald Trump ridiculing him.
A title card then said: "Coming soon".
Trump in the video also told Cohen to go back to school to learn how to be amusing. Oh, and that it might be "perhaps the most unsafe show in the history of television".
Showtime had been running online promos for the mystery show, teasing the July 15 premiere of "perhaps the most unsafe show in the history of television" with a lead character that is "shameless", "unhinged" and "cold-blooded".
