Captain Nathaniel Clegg, Pirate, Hanged at Rye, 1776. Captain Clegg (also known as Night Creatures) is a major production from Hammer Films, presented in Eastman Color. It was directed by Peter Graham Scott and features a screenplay by John Elder. The cast includes Peter Cushing, Yvonne Romain, Patrick Allen, Oliver Reed, Michael Ripper, and David Lodge. Don Banks composed the music, with Arthur Grant handling the cinematography. "The Romney Marshes—flat and desolate—were home to a proud and independent people. Their shores faced France, and many shipments of wine and brandy were smuggled across the sea, defying the King's revenue men. Numerous legends have sprung from this corner of England, but none are as widely believed or feared as the story of the Marsh Phantoms, who roamed the land on dark, misty nights, striking fear into those who crossed their paths.” Hammer’s film is a remake of a lesser-known 1937 movie called Doctor Syn, which starred George Arliss in the title role and featured Margaret Lockwood. For their version of the Captain Clegg/Marsh Phantoms story, Hammer created a colorful, Gothic-style mystery thriller with horror elements. It's not overtly horrific, which has probably discouraged some horror fans who came across it for the first time. This might explain why it remains relatively obscure among Hammer productions—it hasn’t even been released on DVD in its country of origin! The story itself is quite good, involving smugglers, murders, romantic passions, ghostly appearances, and deceptive characters, all presented with excellent period production design by Bernard Robinson for the interiors; the exteriors were nicely filmed around the village of Denham in South Buckinghamshire. Pigeon Pie, Creepy Scarecrow, and the Romney Marsh Phantoms. Naturally, the historical atmosphere and narrative intrigue wouldn’t be much without strong performances. This is another reason why this Hammer film has been overlooked. Peter Cushing delivers one of his finest portrayals—a blend of a dandy with a sly nature—and he's supported by a committed and effective cast. Michael Ripper (as Mipps the undertaker) gets a more substantial role than usual, which is welcome. Patrick Allen (Dial M for Murder) is imposing as Captain Collier, Martin Benson (The King and I) plays Rash convincingly, and David Lodge (The Cockleshell Heroes) provides a strong physical presence as Bosun. Oliver Reed stands out as Harry, dominating his scenes with brooding intensity; Romain (The Curse of the Werewolf) embodies the classic Hammer female type—pretty and busty—inspiring lustful desires in both Harry and Rash. There are some plot holes that observant viewers will notice, and the major reveal is telegraphed fairly early on, around the middle point. However, it’s a worthwhile film that fans of Hammer Films, Peter Cushing, and period mysteries should try to find. 8/10
