One expanded movie I'm curious about is Battle For the Planet of the Apes, which has deleted material in the Japanese laserdisc, I believe, and I think it was aired on TV. Not sure why it's never been included in a US release (nor the Friday the 13th stuff, either), but after the recent spiffed-up original POTA DVD, which nonetheless was just a repackaging of the film with the 2-disc Behind the Planet of the Apes (which itself was a newer version of the old one disc of that), maybe the whole series will be re-released with more extras. And, from what I understand, the first POTA itself has deleted scenes.
