I was starting to foam like a rabid dog just looking at this film poster.
The grammatical pendant in me was infuriated by Cleanskin being written as one word.
However, I stand corrected. A cleanskin is an undercover operative whose identity is not known to the forces he or she is tasked to infiltrate.
But in the UK it has taken on a new meaning since the 2005 London bombings. The four bombers were described by police as cleanskins because their profiles did not fit that expected of bombers.
As it happens, cleanskin could fit either side of Hadi Hajaig's movie.
On one side is Sean Bean, as a former soldier, who is determined, on behalf of his country, to erase every terrorist from the planet.
On the other side are are bunch of extremists, including Abhin Galeya, who are prepared to give their lives for Islam.
Now if that all sounds very cliched, it isn't really - largely because there are huge flaws exposed on either side.
It certainly isn't a simple case of Bean goes after the bad guys.
Indeed, he begins to question who is on whose side. Charlotte Rampling, James Fox and Tom Burke are among those, who, on the face of it, are the good guys.
Galeya's team include Peter Polycarpou, as the typical bad egg - the extremist preacher.
But the skill of Clearskin is in the blurring of the lines. Nothing is quite as it seems and nobody is quite as bad as they seem (well, there are a couple who are pretty evil).
Bean is in good form - tough, yet vulnerable. Galeya is a star turn as the easily-influenced radical.
Overall it is a movie which has deserved a longer run at the cinemas than it seems to have been given.
Laughs: none
Jumps: two good ones
Vomit: one scene
Nudity: Gratuitous raunchiness from Galeya and Tuppence Middleton.
Overall rating: 7.5/10
