Dracula Vs. Frankenstein (1971)

Classic camp with two of filmdom's most famous monsters squaring off against each other in a battle royal is a schlocky treat. J. Carrol Naish (in his final film role) is the wheelchair-bound Dr. Frankenstein, and Lon Chaney Jr. (in his final role) plays a kind of Igor character. With more scenery-chewing than you'd find in a kennel of pit bulls, Dracula vs. Frankenstein is fangtastic!

This was Lon Chaney Jr.'s final horror film role and J. Caroll Naish's last film. Chaney filmed his part in mid-1969 when the film was titled Blood Seekers; Naish filmed additional footage in 1970 when Dracula and the Frankenstein Monster were added to the story.
Forrest J. Ackerman has a small role in the film as 'Dr. Beaumont'.
