Okay, so when I was a kid growing up in Puerto Rico, I remember seeing this weird movie when I was relatively young. As best as I can remember, this movie seemed to be something from before the 80s, though it might be early 80s at the latest. More likely though, this was something from either the 60s or 70s which had just been put on TV and dubbed into Spanish.

I don't know if this was a US film or not and worse, I only remember one scene:

At the very end of the movie, a man and a woman are put into this giant machine. The interior of the machine may have had throw pillows in it. When the machine is turned on, all sorts of 60s/70s psychedelic special effects happen and they are fused into one hermaphrodite-like being that walks out of the chamber to some macabre sounding music...

For some reason that scene always stuck with me, but I have never been able to identify the movie, likely some bad, seldom referenced sci-fi thingy.

A'ight sifters, have at it. Remember that since this happened on PR tv, it may not be a US film... very possibly it was foreign.
