I read Aaron Beierle's DVD review of Chain Camera at http://www.dvdtalk.com/reviews/read.php?ID=16889 and... was wondering about this quote.

"that focuses on the lives of teenagers at John Marshall High School in California - the same school where "Buffy: The Vampire Slayer" and "Grease" were filmed."

I know Buffy was filmed at Torrance High School in Torrance, CA (same as BH 90210). Did they also film at this other school?
