British prints of SCREAM AND SCREAM AGAIN have small differences than AIP's American Theatrical cut, with the American version removing Bellaver clumsily throwing a stone at the speedy cliff-climbing super-human Keith, and a bottle-swigging old drunk peeping at Keith and Sylvia fooling around in the convertible. The final shot of the British print is also different, with the credits scrolling over a long shot of Dr. Browning's lab heard over soundtrack music, rather than on the American print which has the credits being presented over a black screen with The Amen Corner's "Scream and Scream Again" playing. One thing omitted from the American version is a brief but significant dialogue exchange between Vincent Price and Christopher Lee: "But what of the dream?" asks Price. "There is only nightmare" replies Lee).
