I saw "Beyond and Back" only once -- in May 1978 during its initial theatrical run. But the film proved to be a lifesaver -- literally.
It saved my life. I went to see it at a time when I was very lonely and despondent and was contemplating suicide. I was 25 years old at the time and was depressed over what at that time had been an inability to find love in my life -- that is, the love of a companion, having fallen in love with someone fir the first time in my life, only for that love to go unrequited.
I won't spoil it for those who have never seen "Beyond and Back," but suffice it to say, it convinced me that suicide is not a viable option.
Ironically, I recently saw a clip of "Beyond and Back" on YouTube exactly 30 years to the day after I saw it in the theater. It's really cheeky by today's production standards, but it's still worth watching, even if only as a vintage 1970s period film.
