The Fifth Floor (1978)

Has anyone here seen this?

I just found out there is a Blu-ray release of this. I haven't seen it in years and don't remember that it ever got mentioned on the old horror board. I don't remember a lot about it except the basic premise of an innocent girl wrongly committed to a corrupt mental hospital and that it had a lot of fairly big names in the cast including Bo Hopkins, Julie Adams and a pre-Freddy Krueger Robert Englund. The lead actress in it, Dianne Hull, is from my home town.
