Also known as Qui? and Who Are You?, this Léonard Keigel-directed movie has Romy Schneider (Death Watch) as Marina, who starts the movie fighting with her man, Claude (Gabriele Tinti, husband of Laura Gemser), who beats her up and tries to drive his convertible off a cliff and into the sea. He dies — maybe — and she falls in love with his brother Serge (Maurice Ronet), but feels watched all the time. Hence: Giallo.

The cops and Serge want to know where Claude’s body is and who killed him. Then, once he gets with Marina, she starts to panic about everything. She’s not exactly the heroine; she couldn’t care less that Claude died, but you know, if someone was routinely abusing me, I wouldn’t be all that verklempt either when they drove into the ocean. It’s also wild that she’s able to jump out of a moving car with hardly a scratch, but as much as Serge wants answers, well, look, it’s Romy Schneider with those Eurocult eyelashes and heavy makeup, and if his brother really is dead, certainly he should sleep with his contentious lover.

This is also like 70 minutes long, which is just perfect. There’s also a rock soundtrack by Claude Bolling that features two songs, “Who Are You” and “Strange Magic,” playing over and over.
