Barber has stature within the music video industry for his ability to break out of the cliches that have dogged the music video business. Barber's videos convey a classic mood often taken from previous era hits. Barber's ability to be heard as a clear and distinct authorial voice lay in his defining a unique visual style, a postmodern style that relied heavily on the use of classic film and TV clips. For example, Barber referenced Grease in the OutKast music video Roses and the Beatles' Ed Sullivan appearance in the band's video for Hey Ya!. In the process, Barber emerged as a talent and imparted an original image to the hip-hop movement.
Barber spent "$50,000 for a presentation that included motion capture, stunts, concept art, storyboards and sound design" to try to get job directing X-Men Origins: Wolverine from 20th Century Fox. He did not get the job but Fox was impressed enough with it reimburse Barber. Barber is currently working on an adaptation of Gigantor after acquiring the rights from Fred Ladd.
