Quite a good film currently showing on Netflix is 6 Days. It covers the Iranian Embassy siege in 1980 and has Mark Strong as Max Vernon who was the police negotiator, Abbie Cornish as Kate Adie and Jamie Bell as Rusty Firmin who led the SAS raid on the embassy. Unlike the previous film which was loosely based on the siege 'Who Dares Wins,' this film goes straight to the start of the siege and covers the 6 days of attempted negotiation, SAS practice drills, news coverage and the assault.
Quite enjoyed it; there was too much "Kate Adie" and Abby Cornish's performance was more of a bad impression. But otherwise well done.
