This film tells one of thousands - hundreds of thousands - of stories of injustices in 20th century America. A country with such a rich and fascinating mix of ethnicities, but such a deplorable record of dealing with it. The film is "based on a true story" - and a real person - but I imagine most of it is fiction. That's alright: it's a movie, after all, but the scenes portrayed really happened on a daily basis to many, many African Americans. Anybody who thought that San Francisco might be more enlightened on race issues than, say, the Deep South would do well to watch I'm Charlie Walker.I enjoyed watching the film. Unlike another reviewer, I thought the acting was good, and the story unfolded well. Mike Colter was a good Charlie Walker and at the end, where we caught a short clip of the real Charlie, underlined why he was a good choice.
