20 Movie Reveals Nobody Noticed
1. Martha In The Mirror - Deep Red
It's only near the end of Dario Argento's all-timer giallo horror flick Deep Red that we find out the killer was Martha Manganiello (Clara Calamai) - the mother of protagonist Marcus' (David Hemmings) friend Carlo (Gabriele Lavia.
However, it's actually possible for eagle-eyed audience members to figure this out way earlier - right at the start of the film in fact, when Marcus witnesses the gnarly murder of psychic medium Helga Ulmann (Macha Méril).
Marcus instinctively races to her apartment, as you do, and when he walks through the hallway, he passes what appears to be a painting.
But if you take a closer look, you'll see the "painting" is actually a mirror reflecting the face of Martha, who is hidden in plain sight and staring at Marcus.
This effectively reveals her to be the killer about 90 minutes before the movie itself drops the veil in earnest. And yet, how many of us ever spotted it?
