Continuity mistake: At the beginning of the "Let's Call The Whole Thing Off" scene, Eddie already poured the orange juice and put it down before Venom messes with the radio and fridge. We see then symbiote's tentacle pass in front of Eddie's hand, which is suspended in mid-air still pouring. Then we cut back to the original angle and Hardy is about to drink from the glass, the orange juice carton well set on the table. (00:23:05)
Continuity mistake: Carnage pins against the wall a prison warden who begs him to spare him. He looks straight ahead and the POV shot displays Carnage's face directly in front of him, but in the side view Carnage's splotchy eyes are in front of the chest of the guy and the tongue has to go up a lot to plunge inside the victim 's oesophagus. (00:38:15)
Continuity mistake: When Venom starts tossing Kasady around in his cell, Eddie right hand is positioned in the rightmost space of the door. Kasady bites him when his arm is through the space to the left of that, though. His arm is also pointed at a different angle and height between shots. (00:29:35)
Continuity mistake: Venom is drawing hyper-fast parts of the material they ogled on the wall of Kasady's cell. On Eddy's messy desk there's a sheet with data from California State University, very recognizable for the colors and shape of the graph. When they draw the tree, notice that the sheet turns 90° multiple times between shots without Venom touching it. (00:10:50)
Continuity mistake: When Carnage steals the Mustang he is driving through the financial district in San Francisco. It then cuts to him driving into the city on the Bay Bridge. How and why did he go from being in the city to leaving and driving back in?
