A picture of a man is scanned to see if it is Kraven, and the computer says it is a 97.3% face match. Later in the movie, the picture is shown again, and the computer says it is a 99.99% face match.
When Kraven walks into Dimitri's club at the end of the movie, Dimitri is holding the microphone with both hands, then in the full length shot his left hand is in his pocket, then back in close-up both hands are on the mic again.
When the water buffalo herd are intercepting the Rhino's convoy, the men in the first truck to be hit only notice the herd just before their truck is hit. The Rhino already drew their attention to the buffalo being there, and the ground shaking and the sound would have alerted the people in the car well before they were about to be impacted.
Three issues:
One: Rhino did not say what he was seeing, or where;
Two: vehicle suspension - on that dirt track the suspension would have damped out any slight tremors from the running herd;
Three: inside the vehicles, on that dirt track, the sound of the herd would not be noticed until it was almost beside them, as the truck passenger finally did.
The helicopter used to take Kraven to hospital in Africa has a British registration assigned to the Yorkshire air ambulance , a long way to fly to pick someone up .
Kraven slows the helicopter by throwing netting onto one of its landing skids and digging in his heels as it tries to fly away. Although Kraven has super strength and durability, he seems to weigh the same as a normal man, and he is not depicted as having the ability to fly or manipulate objects without touching them. The helicopter should simply lift him off the ground if he's not holding on to anything.
When Calypso is holding the bow and arrow and aims it at Kraven when he walks through the door, in the frame just before she starts to cancel her draw, you can see her almost phase forward. It's hardly noticeable, but for a scene that likely wouldn't require CGI, this seems like an odd and unreasonable mistake.
The shadowed outline of Kraven's profile standing in the payload section of the aircraft, shows his "love handles" with his inhales and exhales. To mean he is wearing no shirt. Yet, when he jumps off the loading ramp in a shirt, it is loose enough to cover his very small spare tire.
When Kraven and Calypso are talking on the balcony of his hideout, the ADR dubbing is very obvious; the dialogue doesn't match the characters' lip movements closely.
Dmitri is obviously not actually singing during the nightclub sequences because he dramatically moves his head with no effect on the audio. To eliminate background noise and feedback, real-life live vocal microphones only pick up sound from a specific direction at a close distance. If the performer moves their head away from the mic, the sound should drop out.
During the final battle a helicopter flies overhead and the camera pans to Kraven where he says: "You've Gotta Be Kidding" which he says with his mouth shut.
There are no African buffaloes in the Far East.
Snow leopards are not native to Siberia.
It is said that Kraven can find his brother in a monastery in Ankara, but it's clearly Sumela Monastery in Trabzon, Türkiye.
