DVD: Red Lights (15)

Bent spoons, country house séances, electrical storms and fraudulent healers feature in this supernatural thriller which, until it unravels halfway through, is rather gripping.

Sigourney Weaver and Cillian Murphy (above right) play academic ghostbusters who specialise in debunking paranormal “hocus pocus”. However, a sinister celebrity psychic (Robert De Niro) proves a harder phony to crack. Elizabeth Olsen and Toby Jones are slightly wasted in underwritten roles, and with a bit tweaking and judicious re-writing this could have been a creepy gem.
