…I guess this might qualify for a SPOILER warning.
Anyway, as per my usual weird habits, I was just racking my, er, brain to come up with a list of movies: specifically, movies that involve a human brain transplant, but not intentional killings.
I came up with two.
•“Who is Julia?” A surprisingly respectable 1986 TV-movie starring Mare Winningham.
•Young Frankenstein.
Even if I fudge the criteria to include “people are killed, but not actually including the brain donor or body donor,”* I can only think of two more; the original Bride of Frankenstein, and 1985’s The Bride. (The Frankenstein movie with Sting and Clancy Brown.)
Can anyone think of any others? There has to be at least a couple more, I’m sure.
*Strictly speaking, that should be “body donor or body recipient.” But you know what I mean.
The OP mentioned “Who is Julia?” which is what I would have put down. As was said it surprised me for how good a TV movie it was, not going so much for sensationalism as for really focusing on the conflicting emotions of the people involved.
According to wikipedia, Lex Luthor once developed cancer due to radiation exposure form the kryptonite ring he was wearing to keep Superman away. Luthor had his brain removed from his dying body and placed in a jar while he had a non-cancerous clone body grown which he had his brain transplanted back into. He also used this as an opportunity to claim that Lex Luthor was dead (using the original body as proof) and set himself up in a new identity as his alleged son.
Except Eunice was killed by a mugger, so that doesn’t count. Yes, she wasn’t killed in order to intentionally facilitate a brain transplant, but she was still killed intentionally.
And there was a Two Guys and a Girl Halloween special like this, “Halloween 2: Mind Over Body.” The body wasn’t killed on purpose, but in a tragic bookcase (?) accident.
How about the TV show Now and Again, where John Goodman’s character Michael Wiseman fell in front of a subway train and his brain was rescued and transplanted into the artificially-built body of a government agency (played by Eric Close)?
