During the breaks between quarters, movie trucks often arrive at UCLA. Yours truly doesn't know what movie is being made this time, but the trucks are there again. However, back in 1989, one of the worst movies ever made - Big Man on Campus (based loosely on the Hunchback of Notre Dame) - was filmed almost entirely at UCLA. We posted about it way back in 2011: http://uclafacultyassociation.blogspot.com/2011/07/uclas-contribution-to-art-of-cinema.html
If you go to the link above, you can see the whole movie courtesy of YouTube.
