Scottish Man's Viral Spanish Prison Story Sparks Major Film Deal

A Prison Band, a National Competition — and Decades Later, a Film Deal

In 1988, Allan McCarthy — a 25-year-old from Barrhead, near Glasgow — was sentenced to six and a half years in prison in Spain for cannabis possession. He served his time at Sangonera de la Verde prison in Murcia. It was, by any measure, a difficult chapter.

What happened inside that prison is what makes the story remarkable.

McCarthy discovered music while incarcerated. He formed a band with fellow inmates — Berlin90, as they became known — wrote original songs, and entered a national music competition. They won. The band earned the nicknames "Jailhouse Rock" and "The Bad Boys of Rock", landed television and radio appearances, and recorded professionally — with police escorts accompanying them to sessions.

Now, nearly four decades later, that story is being turned into a documentary film.

From Social Media Post to Film Deal in Weeks

McCarthy, now 62 and two years into recovery from drug and alcohol addiction, shared his story on social media just three weeks ago, hoping to raise some funding and awareness. He had no expectation of what came next.

Director David Zucker came across the post and made contact almost immediately. Within weeks, a deal was in place. Filming has already begun — first in Glasgow, shot at an Italian restaurant, and subsequently in Edinburgh.

The documentary is targeting a spring festival release, and early discussions are also underway with a record label about new music.

"It's a complete dream and a few weeks ago I wouldn't have believed it," McCarthy said.

Rehabilitation, Recovery and a Second Chance

McCarthy credits a government rehabilitation programme during his incarceration with setting him on the path that led to music — and ultimately to where he is today. The programme gave him structure, purpose and an outlet that stayed with him long after his release.

His willingness to speak publicly about his experiences is now, he says, part of his own recovery process — and something he hopes can help others.

"It helps with the recovery process," he said of sharing his story. "Now I can help people get clean by sharing my story."

On the prospect of new music and the film deal, he was reflective rather than triumphant:

"Maybe no one will like the music, but at least I've got the chance. I've gotten a second chance."

A Story That Resonates

There is something in McCarthy's story that cuts through in a way that polished celebrity narratives rarely do: a genuine fall, a genuine transformation, and a second act that arrived almost by accident — through a social media post and a stranger who happened to see it.

For the large British expat community in Murcia and across Spain, the story of a Scot who ended up in a Spanish prison in the late 1980s and found music there will have a particular resonance. It is a very different Spain to the one most residents know today — and a reminder of how much both the country and the lives of the people who came to it have changed.
