Hmmm, something with Will Hay? He played a few wacky teachers in his time. https://www.imdb.com/name/nm0370547/

Could be one of the (many) Carry On Films: Carry On Teacher https://www.imdb.com/title/tt0052676/?ref_=nv_sr_srsg_0 Or you can look at this list: https://en.wikipedia.org/wiki/Carry_On_(franchise)

Is it this: The Miraculous Mellops https://www.imdb.com/title/tt0101145/

No Problem

Could be What Lies Beneath, but it's Michelle Pfeiffer not Nicole Kidman... https://www.imdb.com/title/tt0161081/

Happy Death Day? https://www.imdb.com/title/tt5308322/

The grand daddy of them all: Rear Window https://www.imdb.com/title/tt0047396/?ref_=fn_al_tt_1 or Disturbia https://www.imdb.com/title/tt0486822/ or maybe, Sliver https://www.imdb.com/title/tt0108162/?ref_=fn_al_tt_1

That's making think of Ed Wood, the Tim Burton Film that is a biography of the terrible filmmaker of the same name. https://www.imdb.com/title/tt0109707/ or the film that Ed Wood made in the 50's that...

Just to mention that there are two Stepford wives movies, the original from 1975 and a remake in 2004. There are also a number of spin offs and sequels that were made for TV. https://en.wikipedia.org/wiki/The_Stepford_Wives

Do you think it was a TV show or a movie? How graphic was it, like horror movie graphic?

Sounds very much like The Call of the Wild; the novel by Jack London, which has been adapted many times most recently with Harrison Ford. I could only find one animated version on IMDB, but I have a nagging...

Could be Re-Animator? It's definitely got a evil talking head... https://www.imdb.com/title/tt0089885/

Just going off your title: Condorman https://www.imdb.com/title/tt0082199/?ref_=nv_sr_srsg_0
