Black Oxen is a slightly curious but enjoyable silent movie. A love triangle but with elements of fantasy and science fiction.
The film stars Conway Teale as a NY writer who falls in love with an Austrian countess played by Corinne Griffith. Clara Bow plays the other side of the triangle, in love with the writer but his attention is only on the countess and not the somewhat annoying flapper...
But the countess has a dark secret, she is using specialised treatments and X-rays to retain her youth and is really a much older woman and not in her twenties as she appears.
She gets found out in the end of course. Well apparently, only seven of the film's original eight reels are extant meaning the end of the movie (about twenty minutes) is now missing. Luckily original reviews can tell us what happens! All spoilers arn't bad.
