Continuity mistake: As the aliens announce their intentions to the people of earth Dr. Marvin walks up to a radio in the back of the lab and says, "If I'm right they'll sail into Washington in broad daylight ". If you look closely the radio is pointing to a different station that it was when we saw it previously in the scene even though no one has gone near it. (01:04:35)????
Visible crew/equipment: During the final attack after Carol falls on the floor in a hallway in the Pentagon there's a shot of a crowd running towards the camera. The woman in the front has the shadow of the boom mike right on her forehead as she comes close to the camera screaming bloody murder. (01:13:25)????
Continuity mistake: After the first part of the exorcism, Father Merrin leaves Regan's room and we see his red prayer book and crucifix sitting on the nightstand as he does. He sits on the steps and then goes into the bathroom to take a pill, but later as he goes back into her room he has the book and crucifix in his hand. (01:53:00)????
Deliberate mistake: After the aliens announce their intentions Dr. Marvin meets with Carol back at their hotel room. He tells her that she must take a flight alone back to Palm Springs and then leaves the room. In the end of the scene she picks up a copy of The Evening Star, which is an obvious prop as it has no date on it. (01:08:50)????
Deliberate mistake: Father Merrin says, "It is He who commands you", and we hear and see the ceiling crack above his head. In the next shot we see the ceiling above him and they are no cracks in it, but four shots later we see the exact same spot and now cracks appear even though we hear no more cracking over-dubs after the first one.
