Its definitely a good one, Hammer always had talent, especially the actors...and the twist near the end is awesome and genius..you gotta love Strasberg's portrayal of Penny, she really did a wonderful job. Most of the actors in the movie fit the roles really well, and i can't think of any other actors who could have done a better job for those roles...whether or not its the greatest is opinion, because there are too many choices within the hammer catalog to choose from which have equal merit.
