Loose Cannons is a 1990 action comedy movie by director Bob Clark, who also co-wrote the screenplay with Richard Matheson and Richard Christian Matheson. In the movie, Mac (Gene Hackman) is an unconvential cop who gets some less than welcomed news: the infamously burnt out, but also brilliant, by the book detective Ellis (Dan Aykroyd) has been assigned to be his partner. The news gets even worse when Mac realizes that Ellis is not only burnt out, but a wee bit off his rocker too. Ellis suffers from split personality disorder, assuming the identities of various characters from the entire casts of television shows. While health should not be a factor in work, that is easier in theory than in practice. When Ellis starts switching into various characters during work"including when the two are being shot in"things get a little interesting. Loose Cannons is a funny movie with a crime spin and enough action scenes to keep most people satisfied.moreless
