Danny Dyer has taken on a new dramatic role portraying a key figure in the 1980 Iran embassy siege in London, a pivotal event in modern British history. The former EastEnders actor is currently filming for Channel 4’s upcoming drama "The Siege," which recounts the six-day hostage crisis that unfolded at the Iranian embassy in South Kensington.

Dyer plays PC Trevor Lock, the police officer assigned to guard the embassy when six terrorists seized the building, taking Lock and 25 others hostage. The stand-off culminated with a high-profile SAS raid, broadcast live on television, which resulted in the deaths of five of the terrorists. Lock, who passed away in 2025 at the age of 85, was recognized for his bravery with the George Medal for his actions during the siege.

According to accounts, Lock kept his firearm concealed throughout the crisis and managed to establish communication with the hostage negotiators by building a rapport with the terrorists. During the SAS assault, he confronted and wrestled the leader of the terrorist group, playing a critical role in the operation’s outcome.

On set, Dyer has adopted the look of a 1980s police officer, featuring a clean-shaven face and a neatly parted hairstyle, a departure from his more rugged, contemporary appearance. This new role reflects an expansion of Dyer’s acting repertoire; aside from starring in "The Siege," he is also appearing in the Disney+ series "Rivals" and will soon co-host ITV’s Saturday night quiz show "Nobody’s Fool" alongside Emily Atack.

"The Siege" aims to provide a detailed, dramatized perspective on one of the most intense moment of modern British counterterrorism efforts, focusing on the individuals involved and the high-stakes negotiations that defined the crisis.
