Irish filmmaker Jim Sheridan is set to write and direct a new drama about Pan Am terrorist bombing over Lockerbie, Scotland.

Jim Sheridan is preparing to bring the story of the 270 passengers and locals who lost their lives in 1988 when Pam Am Flight 103 was blown up over the Scottish village Lockerbie to the big screen. 

The My Left Foot director has teamed up with screenwriter Audrey O'Reilly to develop a script that he will direct.

The story will centre on activist Doctor Jim Swire, who lost his daughter Flora in the tragedy. Swire has always maintained Abdelbaset al-Megrahi, the alleged Libyan intelligence officer who was jailed for the bombing, was not guilty. 

Megrahi was released from prison on compassionate grounds in 2012 after he was diagnosed with terminal cancer.

Sheridan hopes his film will help to answer many outstanding questions about the Lockerbie bombing.

Speaking about the project Sheridan told The Hollywood Reporter, "It's scary what they didn't reveal to us at the time. It doesn't really matter, the people are dead and you can't bring them back to life. But in the future, we need clear investigations of these things."
