I made a bunch of experimental super-8 films in college and then attended an MFA program in film production at Temple University. Temple's program encouraged its students to learn all aspects of film production and did not follow the industry model at all. There was no structure where you played at being "the director," "the writer," or "the producer," an approach which I think is unhealthy. There's enough time to experience the hierarchy of film business later on, and I think the most important education you can have if you want to direct films is to learn every aspect of the process.
On paper Brothers of the Head looks gimmicky ("conjoined twin rock and roll band mockumentary"), but it's smarter than that -- intense, demanding, and weird (as in "Ken Russell weird"). Definitely not your typical summer fare. Go see it.
