I could find very little information on this film. Critic Chris Fujiwara had this to say about it:

"In the furious The Girl in the Rumor, as tight, absorbing, and intricate a 55-minute film as any ever made, a confrontation between two sisters is staged and cut as a series of complementary, mirroring, responsive movements in and out of frame, resulting in a dizzying pattern in which the two sisters ceaselessly replace each other. Much of the visual shock of the film comes from the intercutting of shots in which one or the other sister is alone in the frame with shots showing one in the foreground and the other in the background (alternately in/out of focus). The visual equation shifts and surprises."

For being such an obscure film, the print quality is quite good! Enjoy.
