Thanks for a tip regarding the music videos. I'll check them out, but as far as I can remember those, they haven't had any Ferris clips. The spin off series was really unwatchable and is not of interest for this project. The original DVD release has newly created featurettes with some segments from vintage Electronic press Kit (see below). If we could get our hands on the EPK that'd be nice...

"Getting the Class Together: The Cast of Ferris Bueller’s Day Off" - featurette (27.44)
"The Making of Ferris Bueller’s Day Off" - featurette (15.26)
"Who is Ferris Bueller?" - featurette (9.06)
"The World According to Ben Stein" - featurette (10.51)
"Vintage Ferris Bueller: The Lost Tapes" - featurette (10.01)
"Class Album" - photo gallery (18 images)
