Although Denise Richards' character is named Tammy in the film, the beginning and end credits list her as "Tanny". That is the name used in the original title, "Tanny and the Teenage T-Rex", as given in the uncut version released on 4K and Blu-ray by Vinegar Syndrome.
The local county sheriff deputy inexplicably drives a LAPD car.
Tammy and Byron open Michael's coffin and see that his body is decayed, but he's only been dead for one day.
The camera and dolly are reflected in the side of the black car when the T-Rex goes to attack Billy while he's having sex with the girl.
When the doctor is performing the initial brain transplant and experimenting with stimulating Michael's brain to cause his body to react, the first reaction causes his leg to lift. It's too obvious that a female crew member's hand is holding a fake phallus under the hospital gown, which he lifts during the next "body reaction."
When Billy and his gang are chasing Michael from Tammys house a crew member can be seen crawling in the road as the Jeep is pulling away.
Wire visible when the T-Rex lifts up Billy.
Towards the end of the movie when Tammy and the T-Rex are in the barn, on a long shot a hand and arm can be seen at the dinosaurs tail seemingly tickling it.
Tanny (original cut title name)/Tammy (Denise Richards) wails that they put Michael's brain into the dinosaur, but a replacement 'transplant' into the T. Rex never occurs; his removed brain is first used to 'operate' the T.Rex from outside it.
The shadow of the boom mic appears in the upper left corner of the screen when the pizza delivery boy runs out of the laboratory scared.
