[1] The northernmost part and scenery of Kalsoy was used as stand-in for the Kuril Islands in eastern Russia while filming for the 25th James Bond movie No Time to Die.

In the film, which was released in 2021, the villain's lair is located on the island, for which a harbour and missile silos were added digitally.

The western coast has steep cliffs for the full length of the island, whereas valleys on the eastern slopes protect the four tiny settlements, Húsar, Mikladalur, Syðradalur, and Trøllanes, whose combined populations total less than 80.

The island's thin shape and road tunnels give it the nickname "the recorder" (Faroese: blokkfloytan).

Ferry landings occur at Syðradalur, and one of the mail boats (named Sam) makes regular trips from Klaksvík to both settlements.
