Public Access TV can be glorious, or it can be horrible, or it can be somewhere in-between, but it's always the efforts of your neighbors creating their own vision on a low budget and big dreams. A retrospective of one of the better efforts to create a show, 20 Years of Madness, will be showing this weekend at downtown's Screening Room as part of the Arizona International Film Festival. And it will benefit Access Tucson, our own public access station that has been on the ropes as city officials have steadily cut its funding and threatened to sell its downtown headquarters in recent years.

Here's the film's description. There's a warning that you'll see nudity and hear bad words:

20 Years of Madness is a feature-length documentary following Jerry White Jr., founder of the Public Access TV Show 30 MINUTES OF MADNESS, as he leaves Los Angeles and returns to Metro Detroit to make a new episode on its 20-year anniversary. Jerry reconnects with the friends he grew up with as they discover whether the magic of their show was a fleeting youthful experiment or a creative community they will share for the rest of their lives.

The film shows at 1 p.m. on Saturday, April 18. More details on it and the rest of the Arizona International Film Festival here.
