The December 1988 terrorist bombing of the London to New York Pan Am Flight 103 continues to reverberate.

All 259 passengers and crew were killed when the plane exploded 38 minutes after take-off, killing 11 more as the plane crashed on the quiet Scottish village of Lockerbie.

“Lockerbie: A Search for Truth,” streaming Jan. 2 on Peacock, examines the multiple cover-ups and investigations in that disaster’s wake.  Much of it led by Colin Firth’s Dr. Jim Swire whose daughter Flora was among those murdered. He was elected to speak for the families of the UK victims.

“He essentially dedicated his life to exposing how, despite intelligence agencies being alerted, that was covered up and this disaster happened,” director Otto Bathurst said during a virtual press conference from London. “What struck me was the core of the story — it’s the title actually, ‘Lockerbie: A Search for Truth.’ What blew me away, here is one man just relentlessly searching for that truth.

“The fact is that the British government, the American government — they lied to him. His daughter should never have been on that flight. And that, as a purity of story, is just incredible.

“That is the truth. I found that incredibly inspiring and incredibly amazing. Then you have all the conspiracies, the media and all the craziness that goes on (for years). We tell that story over five episodes, this immense spider web that Jim gets embroiled in.

“But ultimately at the end of the day that is the simplicity of it.”

Firth, 64, knew the importance of playing this man whose relentless pursuit unlocked so many doors and windows. He had read Swire’s book, “The Lockerbie Bombing: A Father’s Search for Justice,” which was adapted for the series. He met Swire.

“I found that Jim got straight to the point. He asked me questions. There wasn’t a lot of small talk. And then, it wasn’t all about this. I mean, he also made me laugh.

“But the alertness and the intellectual agility made me feel I really had to catch up and keep up.

“It’s 35 years now and it’s impossible to imagine that that’s how long,” Firth continued. “It feels far more immediate than that. When I was sent this script, it had an emotional impact.

“It was less the legal investigation-thriller element and far more how it just made me feel, seeing this representation of Jim and his wife Jane and their family. And this journey that, having carried this for so long and still carrying it, how many steps? How many twists and turns?

“He let evidence and facts speak to him, even if that meant profoundly changing course. That really, really struck me.”
