Island of Terror

Island of Terror is a 1966 British horror film released by Planet Film Productions. The film was released in the US by Universal Studios on a double bill with The Projected Man 1967. The idea for the film came when Richard Gordon read the Gerry Fernback screenplay The Night the Silicates Came. He partnered with Tom Blakey of Planet Films to produce this movie.

On the remote Petries Island off the east coast of Ireland, farmer Ian Bellows goes missing and his wife contacts the local constabulary. Constable John Harris goes looking for him and finds him dead in a cave without a single bone in his body. Horrified, Harris swiftly fetches the town physician Dr. Reginald Landers, but Dr. Landers is unable to determine what happened to the dead mans skeleton. Landers journeys to the mainland to seek the help of a noted London pathologist, Dr. Brian Stanley.Like Landers, Stanley is unable to even hypothesize what could have happened to Ian Bellows, so both men seek out Dr. David West, an expert on bones and bone diseases. Although Stanley and Landers interrupt Wests dinner date with the wealthy jetsetter Toni Merrill, West is intrigued by the problem and so agrees to accompany the two doctors back to Petries Island to examine the corpse. In order for them to reach the island that much faster, Merrill offers the use of her fathers private helicopter in exchange for the three men allowing her to come along on the adventure. ........
