After some of the episodes of the show leaked online last year, the producers are reportedly taking some extreme measures to protect “Game of Thrones” Season 6. Meanwhile, a new report reveals how the production of the show got delayed, while they were filming the Castle Black scenes.

While filming at the Magheramorne Quarry in Northern Ireland, the production crew experienced a rockslide, Entertainment Weekly reports. Most of the Castle Black scenes are filmed at this location. The location apparently receives a lot of rain and filming is said to have taken place during an extremely cold winter and there was plenty of rain.

Executive producer Dan Weiss revealed that at first the crew on the set noticed small pebbles rolling down and that later turned into larger pebbles. “A piece of rock the size of a London townhouse just fell,” Owen Teale (Alliser Thorne) said. “Everybody made the group decision to immediately step away from the set,” the producer said.

Every year, the big budget TV series has to be produced on a tight schedule and “Game of Thrones” Season 6 was no different. The rockslide led to some delay of filming, but thankfully no one on the set was hurt.

The cast and crew managed to complete the filming process and the show is set to return in April with no delay. Promotion of the TV series is ongoing in full swing and the producers are taking extra precautions to make sure none of the episodes leak online.

While the members of the press are not getting advanced screeners of the TV series, fewer people even got to see the full script, Tech Insider reports. HBO affiliates across the globe will only get the episode closer to its air time. The producers also reportedly used code words while talking about some of the characters and scenes in “Game of Thrones” Season 6.
