X-Men Origins: Wolverine (2009)

Factual error: When Wolverine leaves one of the compounds, he slashes through the door with both hands, creating an "X" in the door. After the second slice, the portion of the "X" where the cuts actually crisscross remains in the door, when in reality the pieces would fall out as they wouldn't be attached to the door any longer and would be floating in air. (00:44:30)

Stryker: Your country needs you!
Logan: I'm Canadian.

Trivia: In the end where Wolverine is freeing the mutant prisoners, one of the prisoners is tied up, seems to be trying to run out of the cage and has white hair. This is Quicksilver, Magneto's son.

Question: Given that Logan's body (skin, bone, muscle, etc) is what "regenerates" quickly, and Adamantium is absolutely fixed once it is solidified, Logan would now have two permanent holes in the front of his skull from the bullets fired into his brain to destroy his memories at the end of the film? Unlike the skin, muscle, bone and brain tissue, the Adamantium would not "heal over" or regenerate, so the two vulnerable bits of bone would remain, a bit of a vital vulnerability in a dangerous area of the body.
