Baker started making short films in the late 1980s. Some of them have aired on PBS, The Learning Channel, and Canadian and Australian television. His films and style have been recognized in publications ranging from Runners World to Filmmaker magazine.
Baker has spent the last six years touring the US teaching his unique and scrupulous brand of filmmaking at workshops and showing his films to audiences at art house theaters, colleges, universities and media art centers. His methods might be considered guerrilla film making. For example, on the set of the Gas Cafe, Baker received permission to shoot in a local bar after closing, eliminating the need for a costly studio or constructed set. He set up all his lights on the rigging in the ceiling of the bar. Therefore, as soon as the place closed for the day, all Baker needed to do was turn on his own set of lights and shooting could commence.
Using the money he made from Good Will Hunting, Kelley financed his first feature film, Birddog (1999), the story of used car salesman, Harv Beckman, operating in a trashy part of town. Beckman accidentally comes into possession of a rare 1948 Kaiser automobile, stirring up disturbing revelations about the facts behind the 1948 Vanport, Oregon, flood that destroyed an entire community. The film explores racism, greed, and class in a very corrupt city. It opened the 2000 São Paulo Film Festival in Brazil, and one critic referred to Kelley’s style as "Bruce Springsteen meets David Lynch".
The Gas Cafe (2001) has been called "an old Twilight Zone episode, that has collided with Samuel Beckett’s Waiting for Godot". Five people collide in a bar one night. The twist? One is dead, one never lived and the other three are lying. Shot in digital video in just 8 nights and made for $4000, the movie was said to have been funded entirely on unemployment checks.
Kicking Bird (2005) is about a 17-year-old high school student, Martin "Bird" Johnson. Considered nothing but white trash, Johnson's mother is in jail, his father gone, one brother in a work camp, and a bitter grandfather who beats him. When the greedy high school track coach sees Martin outrun his whole team, he realizes the boy may be his ticket to a college coaching position. The film was shot with digital video in 18 days with a budget of $5000. The Runner’s Gazette says, "Kicking Bird Kicks Butt!"
