The "DVD Description" near the top of the page, just under the "Product Details" is for the original 1970 film (Dir. Robert Fuest, writers Brian Clemens and Terry nation) with Michele Dotrice and Pamela Franklin:-
But the DVD cover illustrated and the Customer Reviews are for the 2010 remake (Dir. Marcos Efron) with Amber Heard and Odette Annable:-
I have not yet seen either one, but the reviews here and on the IMDB rate the original film more highly than the remake.
