This is a seriously funny film, for so many different reasons. If you like the dynamics of Meadows and Considine in films such as Dead Mans Shoes and A Room for Romeo Brass then this film will amaze you.
Firstly Considine has a real East Midlands English edge to him when he acts with Meadows, those shifty unpredictable eyes, and that stare that lasts a little bit too long. Naturally he is a scary actor, and so to see him become a goofy, comedic clown is so surprising it takes half the film to convince yourself it's actually him.
The film is improvised and yes they probably shot miles of footage for the 71 minutes used, but my God they looked like they were having a great laugh. Meadows can often be heard pissing himself laughing in the background when Considine throws out some serious offbeat ideas (and words). This in itself made me laugh.
The comedy is funny because it feels quite natural, you spend most of the time laughing at the characters and the anecdotes they spill, more than you do at the situations they are in, which adds something really interesting to the film, it's not a slapstick for the Americans.
The film holds together fairly well, but I didn't really care about that, I just enjoyed laughing out loud to it. I would recommend though watching Dead Mans Shoes just before to give you an amazing contrast, and sharpen the experience.
Like I said it's funny, entertaining and if you like any of the actors or meadows in it - it's a must see. I just wished I was there when they shot it.
