Help with another Eighties Sci Fi film..

[interloper]

Back in the early eighties I started watching a film, the basic premise was that a shuttle astronaut gets hit by some kind of ray or beam whilst on a space walk. He's injured and hospitalised, he recovers but his behaviour is a little odd and he manages to guess a 4 digit code for a door lock.

Unfortunately being fairly young I was sent to bed at this point! Any ideas what it might be? I've trawled IMBD and before anyone says "Quatermass Experiment" or "The Astronauts Wife", the first is way too old and the second is far too recent although the plots are similar.

Nice one, that may well be the film.

I remember watching that donkeys years ago, when very young.
