Like the user below, I saw this late one night on the BBC about 20 years ago - probably the only place it's been seen in the English-speaking world-! The plot as I remember it goes something like this: There are two twin brothers sharing an apartment. One is an untidy layabout, the other is a time machine pilot for a company that does tourist trips into the past. The smart brother is engaged to a nice girl whom the slob brother is also in love with. One of the time machines is hijacked by a group of Neo-Nazis who want to give Hitler the atom bomb (there is a scene of Hitler watching a movie of the fall of the Reich, brought to him by these people to prove who they are). Something goes wrong, of course, which somehow results, in the present day, of the smart brother, his girlfriend and all her family falling off a balcony to their deaths. The slob brother is left to sort things out and somehow manages to return to the present before he left and take the place of the dead brother, and marry the nice girl, who now isn't dead. So there are now two of him, one pretending to be the dead smart brother. If anyone else can add their fuzzy memories to this page please do - eventually we might be able to reconstruct the whole story; it seems unlikely we'll ever get to see the film again-! Maybe it only exists in another time continuum.
