I have very faint memories of a TV movie I watched in the UK in the 1980s.
There's (I think) a montage of short clips near the start,the one I remember shows a runner is jogging along in a tracksuit, the next image he is lying on a hospital gurney staring in horror at two bandaged stumps where his legs used to be.
The plotline I recall is somebody is doing like a Dr Frankenstein but with living body parts. I'm not sure if the villain wanted to create a super athlete body for himself and get his brain put in or if he was making a deadly assassin.
I thought it might have actually been a 'The Avengers' or 'Man from Uncle' story that my memory has confused but I can't find a match.
