When Cale talks to reporters outside the building she says, "deep emotional reaction," but when it's replayed on a TV screen later she says, "deep emotional response."

The warbeast running speed changes from extremely fast (in first person view) to very slow (in frontal view).

Raimi kicks the warbeast into a cable drum and goes for the hoist. The warbeast takes a moment to recover and follows them. When the warbeast starts running from the cable drum you can see Raimis outstretched leg, proving this shot is a reversed re-use of the earlier kicking shot.

Raimi tears apart the four padlocks at the service hatch, but the shackles remain in place. When the warbeast breaks through the hatch, the shackles are gone.

In several scenes the warbeast is spinning its head infinitely. However, there are hydraulic hoses between the jaw pistons and the body which would wind up in this case. In the Core Containment slow motion head spinning scene, one can clearly see that these hoses have been disconnected to allow the spinning.

The scene in the elevator when the Warbeast raises his head and clicks his jaw before attacking Raimi is shown backwards. At the end, one of the jaw pistons falls off the head of the Warbeast, but since the scene is backwards, it starts with the piston attaching itself to the head.

When Carpenter walks through the glass doors and looks back behind him, two cameramen in blue jeans are reflected in the glass.

When the Warbeast attacks Raimi and Weyland in Vault 10, they defend themselves by firing their rifles at it. Why would they do that, when then know well that they have only blanks in their guns?
