Factual error: In the film the scientists are discussing the growth rate at which Lt. Col. Glenn Manning is experiencing. The scientists explain that the heart is made up of just one cell, but this is not correct.

Continuity: In the film Glenn Maning has already reached a height of 30ft. The Army is keeping him in a tent and a military personal brings Glenn a whole turkey on a plate. Then Glenn takes a piece of the turkey meat and holds it in his hand. Being that Glenn is now 30ft tall the regular turkey that the man gave him is now a huge hunk of meat in Glenn's hand. in others words the turkey is not scale in relation to Glenn's size.
