I watched a black and white film (over 15yrs ago). The film was about 2 people (man & woman) living seperate lives. I think that they both end up in some kind of accident (maybe not the same accident). However, they both die and go to heaven but, end up being reincarnated, one as a horse and the other either a dog or cat???? Sorry to be vague only it was such a long time ago. Is a great film tho.
