Something didn't make sense at the end*SPOILERS*
At the end, when Frank's fiance', who framed him, killed his brother on the dentist's chair. Then Frank found the body, extracted his own teeth and had put in his brother's mouth. Then he blew up the office, and, because Frank's teeth were in his mouth, the police thought it was the body of Dr. Frank Sangster.
As a result, Frank's traitor fiance' was thought to have killed him. The hidden camera picked up her shooting the brother, and even though we couldn't see his face,we could still hear his voice. So wouldn't the police know that isn't Frank's voice? So I was kind of puzzled.
It wasn't the best movie in the world, but Novocaine was still entertaining, nevertheless.
