The Reptile (1966)

Harry (Ray Barrett) inherits a cottage in Cornwall, into which he promptly moves. While investigating the cause of his brother's death, he uncovers mysterious happenings that have the townsfolk spooked and silent; it seems they have something to hide. And perhaps they aren't the only ones.
You're not likely to find it on many best of Hammer lists, but overall The Reptile is a decent slice of period horror, with enough intrigue, dramatic moments and dialogues amid the occasional silliness to keep fans happy.
Perhaps best of all was seeing Hammer regular Michael Ripper in such a sizeable role; they ought to have given him more to do in their oeuvre.
