The Man Who Broke Britain (2004) | BBC Docudrama 

A compelling dramatised documentary designed to reveal the fragility of financial trading systems. Shortly after a terrorist strike wipes out much of Saudi Arabia's oil production, a trader disappears from a UK investment bank, leaving crippling debts behind him. Then the bank is declared insolvent, the Saudi-born trader is found dead and a tape surfaces suggesting a possible connection with al-Qaeda. Britain soon finds itself plunged into a deep recession. Tim Pigott-Smith narrates.
