Revealing mistake: If you look at the drawing in front of Eddie when he glances down at it after Venom typed in the name of the beach, it's only a crude draft of the one in close-up (it's missing the wave lines below the cliff outline, for instance). (00:11:20)
Revealing mistake: When Venom violently opens the large portal of the church, he barely takes one step but the doors close basically through him. (01:08:15)
Revealing mistake: The back of Cletus Kasady's head appear quite different between the semi-POV shot in the car (stunt driver) and the next shot when Woody Harrelson steps out of it and gets to the gas station where he will 'hack the internets'. (00:49:40)
Revealing mistake: Kasady squishes a spider that is walking on the postcard. The splattered blotch, strictly divided in red and black, is disproportionately large for the size of the insect. (00:25:35)
Revealing mistake: In a random act of road rage, Carnage sticks out a couple of tentacles, effortlessly lifts up a truck that was driving by, and tosses it off the bridge. Great, but no matter how strong Carnage and each tentacle of his is, it can't nullify physics; it lifts that vehicle stopping entirely its momentum, and Carnage's car does not even remotely budge for the added weight. (00:45:25)
Revealing mistake: Shriek's scream is strong enough to cause the explosion of a helicopter at great distance, but the frame of the windshield is unscathed. (00:54:15)
Answer: If they conducted a one-on-one interview, Eddie might've risked sharing some personal things to get Cletus to open up more. Eddie also took her leaving pretty hard. He might be one of those people who, you spend five minutes talking to them and they're GOING to bring up their ex.
