Despite the comedic title of the film, this is no comedy. Instead it is a well enacted tale of friendship, loyalty and righteousness. Nick Cheung plays Fred, a cop who's been undercover for more than five years now and is understandly a little rough around the edges. When an operation goes wrong, Fred finds himself being framed for his partner's death and a missing suitcase which contains HK$20 million dollars. Under difficult circumstances he realises that the only person who can help him is Dr. Ko (Francis Ng), a police coroner. The two unlikely partners try to solve the case but soon find themselves on the run from the police. With luck, they figure out that the mastermind behind everything is Fred's own superior.

This is a good little film. For once, we don't get to endure Nick Cheung's imitation of Stephen Chow, nor do we get to see his often puerile comedic antics. This is a straight and straight acting affair for Cheung and he equips himself well into his character. We actually sympathise with him as he tries to avoid the authorities while trying to clear his name.

The surprise part in this film is the cast against type of Francis Ng in the role of the rich but lonely coroner. With his well-pressed clothing and bow-ties, he seems out of character, but with a versatile actor such as Ng, he seems to be able to pull it off with ease. Everyone who has seen Ng in his numerous portrayals of triad gangsters and hard-boiled cops will be pleasantly surprised.

Clean my name, Mr Coroner is a great story of two complete opposites, who find themselves warming to each other in a manner they wouldn't have perceived possible earlier on. Fred finds Ko a nuisance, completely out of reality and a goody-two-shoes to boot; Ko finds Fred rough, without manners and is simply rude. But fate brings them together and they soon forge a solid friendship based on trust and understanding.

Ti Lung turns up a good performance as Officer Lau who frames Fred and is the real culprit behind the stolen money, although he did it for a real good reason. And in the end, it is the good-heartedness of Fred that he lets his superior go.

Stephanie Che is the love interest of Fred, and although she brings with her a cool resilience to Fred's charms, she soon finds herself warming to this lonely wanderer, and could not help but take Fred and Ko into her home when they are on the run.

The film offers little in the way of action, and is more of a drama suspense than a gritty actioner. However, there are also some plotholes throughout the film, but you can't expect perfection from such a low-budget film. Nevertheless, very enjoyable.
