Quatermass Experiment, The
This was an early BBC scifi TV series. Professor Quatermass is in charge of the first manned rocketship to go into space. The rocket is launched from Australia, and then goes off course and crashes in Wimbledon. The rocket is found and and only one of the astronauts is still in the ship, and he starts behaving strangely and undergoing a weird transformation. The DVD set linked to is Region 2 (European), as that is currently the only one available.
