When Carl is "delivered" to the security building in a crate, and breaks out of it to investigate, a previous outside shot of the building is shown and his yellow Mustang is shown. He didn't drive to the building at that point, he was delivered in a crate.
Jack Flaherty tells Kolchak that they have reached the 10,000 foot level. There are no elevators that can reach that level.
When Kolchak is hiding in the shipping crate, no matter which angle the box is when it is being moved, he is always shown upright and level.
When Kolchak enters a room with a flashlight, the entire room lights up and shadows are cast towards him. The flashlight itself doesn't give off much light and the light really comes from an off camera source from a different angle.
When the armed men outside the lab confront the lizard, only two guns actually fire and the sound of gunfire continues even after the men use their guns as clubs.
Toward the end of the show, Kolchak finds the pod in the office and removes an egg from inside the pod. He figures out that is what the creature is after. He puts the egg on the table and puts the pod on the cart and returns to the room to make a torch. He finishes making the torch on the table by the egg which is still on the table. When he heads back to the cart, he leaves the egg on the table. There were other eggs in the pod but to attract the creature, he probably would have put the outside egg back into the pod so the creature would not come back looking for it.
