Other mistake: When they have the baby Rex and the parents approach for the infant, there's an outside shot of the T-Rex roaring as Ian moves away to the other side. After he does that the Rex on the other side silently roars, then that same roar bit is repeated from inside the trailer in the very next shot, but the roar is added in, showing repeated takes.

Other mistake: In the shot where the elevator door opens after the screenwriter hears the music playing, the control panel (for the basement) shows the building goes up to eleven floors. When the elevator opens on Floor 5, we can see the control panel on this floor only goes up to ten floors, despite being in the same building. (00:41:55)
Other mistake: When Roper and McCall switch places in the tram scene, Roper steps up on the seat while McCall grabs the wheel. Despite the delay between Roper's foot leaving the gas pedal and McCall getting into the front seat, the car does not slow down. (00:57:20)
