Winnebago Man follows Ben Steinbauer as he sets out to find the titular man also often known as "The Angriest Man in the World." This trailer will bring you up to speed.
The obvious pitfall of a documentary like this is that there is a fine line between the respectful and the exploitative. Given the fact that the film is about a man whose claim to fame is being the star of a viral video in which he is freaking out while shooting a corporate sales video for the Winnebago. Director Ben Steinbauer definitely manages to keep the tone of the film respectful, which is an attribute to the film. The result is a portrait of an acerbic and curmudgeonly yet well-spoken man with a healthy amount of affection for its subject. More importantly, though, it is funny in large part because Jack Rebney is funny.
