Watership Down, the film that traumatised a generation of children, is to be remade for a new era - with significantly less horror and bloodshed than the 1978 animated feature.

The BBC and Netflix are producing the four-part series, and executive producer Rory Aitken has said: “While we won’t shy away from the darkness in the book, visually it won’t be as brutal and scarring.”

The 70s version was unarguably terrifying - but was far from unique in that respect. The 1970s and 80s were a golden era for films and TV shows that set out to scare kids.

Below are 10 of the most terrifying TV series made for children - but have we missed any out? Tweet us at @TelegraphTrend to let us know.

1. Children of Green Knowe

Originally broadcast on BBC1 in the winter of 1986, the supernatural drama was based on a series of children's novels by Lucy M. Boston. A boy called Tolly spends Christmas with his Great Grandmother at Green Knowe, a large old house - where he befriends his long-dead relatives, and has a run-in with a demonic tree-spirit.
