A quarter of a century before a Robert-Shaw-devouring shark had the final word in aquatic menace, there was the Creature From the Black Lagoon. Actually, this dude is even more menacing. He has legs, and can leave his watery environment in search of lady flesh. The amphibious sex pest gets a special screening tonight in the Darwin Lecture Theatre, University College London, part of an ongoing cryptozoology fetish from the (currently closed for rehousing) Grant Museum. The film starts at 6.30pm tonight, with an introduction from UCL's Joe Cain. It's free, and there's no need to book.
