Colin Firth on Playing Dr. Jim Swire in 'Lockerbie: A Search for Truth'

In the new Peacock limited series Lockerbie: A Search for Truth, actor Colin Firth (The Staircase) takes on the challenge of portraying Dr. Jim Swire, the grieving father and tireless advocate for justice in the aftermath of the 1988 terrorist bombing of Pan Am Flight 103 which killed 243 passengers, 16 crew members and 11 Lockerbie residents on the ground.

For 24 years, Swire took point as the spokesman for the coalition, UK Families Flight 103, which expressed the interests of those who lost family in the bombing. As such, Swire became a thorn in the side of the U.K. and U.S. governments, lambasting their response to the tragedy and bringing to light the lax security of airports in both countries post-bombing.

While Swire's actions were bold and defiant, the man himself was actually very reserved and unassuming, a countenance that Firth captures with remarkable fidelity in the series.
