David Tennant will star as poisoned former Russian security agent Alexander Litvinenko in a new ITV drama.
New pictures show the Scots star in a hospital bed, replicating a picture of Litvinenko that made international headlines before his death.
The ex-KGB officer died from Polonium-210 poisoning in November 2006, triggering one of the most complex investigations in Metropolitan Police history.
It is widely believed the Russian defector was poisoned on the direct orders of president Vladimir Putin.
Written by screenwriter George Kay, the drama – named Litvinenko – will tell the story of two police officers called to University College Hospital in London to interview a patient in declining health.
During the police interviews, Litvinenko provided meticulous details from his hospital bed about the events leading up to his illness, which he knew would prove fatal.
His information ultimately helped detectives track down two Russians who had poisoned him with Polonium-210, a highly toxic radioactive substance.
The four-part drama will be streamed on the new ITVX platform, which launches in December.
It also focuses on the story of his widow Marina, who fought to persuade the UK Government to publicly name her husband’s killers and acknowledge the role of the Russian state in his murder.
The drama also features Scots actor Mark Bonnar and whilst Neil Maskell.
Tennant’s return to Doctor Who was recently announced, with new episodes due to appear in 2023.
