Old question answered (finally)

[Bargle5]

About 2 years ago I posted a question trying to identify an old movie from the 60's. I described it as being about trying to figure out who had killed an investigator of some sort. Some doctors/scientists had manged to keep his brain alive in a large tank of liquid and they were able to extract recent memories from it. There was a sequence of a car speeding along a futuristic highway at the beginning. It was very obviously a model car and landscape. While no one  at the time came up with an answer, some people wanted me to let them know if I ever found out what it was. I recently found a good description of the movie and was able to identify it as;

Toter sucht seinen Mörder, Ein (1962) also known as
The Brain
Vengeance
A Dead Man Seeks His Murderer
Over My Dead Body

It's a German film from the 60's loosely based on the Curt Siodmak novel "Donovan's Brain". Some of my recollections about were a bit off, not surprising after 30 years, but this is it.

Thanks to everyone who tried to help. Sorry it took so long to get back.
