University of Southern California's Summer Production Workshop
 
USC offers a broad variety of film making courses during May-July--starting
19 May.  Apparently you do not have to have previous film making experience
to take some of them.
 
The brochure I got on this workshop was a bit hard to decipher.  Best to
contact them for more info:
