I think you'd fit in really well at Brandeis, for the reasons you already mention. The Film program is small but active. I know a couple of people who were in the program and are now either at or heading to film school in California ( I think one of them is about to be an intern at Columbia pictures) - one of them is currently shooting a short film in Boston before heading to film school. The program director Alice Kelikian is very passionate about the program and has helped organized many screenings - one of the highlights during my time there was a screening of the movie Nothing but the Truth with Alan Alda and Kate Beckinsale. Debra Granik, the producer of the Oscar nominated film Winter's Bone is a Brandeis graduate, she recently returned to Brandeis.

to look at the course listings.
There are also film festivals on campus, such as the Sundeis Film Festival and the IndieLouies: Highlighting 'Indie' student talents - Arts
For more info you could also e-mail the Undergraduate Student Representatives from the Film Studies or other program and I'm sure they'd be happy to answer questions: UDRs 11-12 | Brandeis University
and you could also e-mail Professor Kelikian.
I didn't take any creative writing classes, but I know people who did and they seemed to enjoy their classes, and there are at least two or so creative writing publications on campus. Hope that helps! Good luck!
