A "dramatised documentary" based on what would happen if Prince Harry were to be taken prisoner while serving in Afghanistan was described today as "deeply distasteful".
The 90-minute film, called 'The Taking Of Prince Harry', features contributions from former hostages.
The programme includes scenes showing the prince, played by actor Sebastian Reid, being held behind enemy lines while negotiations are carried out to free him.
At one point he is shown having an unloaded gun pointed in his face before one of his captors pulls the trigger, and he is also made to appear in Taliban and al-Qa'ida propaganda.
The programme, which will be broadcast on October 21 at 9pm, also includes scenes where the prince is confronted by a British-born radical Islamist and details how the British government's approach to hostage negotiations differs from other nations.
Harry served in Afghanistan's Helmand province. His presence in the country was hush-hush because of worries he could become a Taliban target.
He spent 10 weeks working as a forward air controller until his cover was blown on the internet. Harry was flown home in February 2008 when the secret was leaked.
Channel 4's head of documentaries, Hamish Mykura, said the broadcaster had informed Buckingham Palace about the film, but had not had any response.
