Michael Cullen slept from Liverpool's sleep roughly, raising £1m for a charitable walk in all Feng Shui in his swimming trunk. Now, his story is being celebrated in a stage musical.

Just as Clark Kent turned Superman when he turned into the famous red panties, Michael Cullen became Speedo Mick when he pulled his blue blue trunk tight.

Coulen smiled and said, “I know a little about how Superman feels when wearing her panties.”

"When I entered Speedos, I did feel different. What happened. It changed. I became more fearless."

Speedo Mick doesn't have Suerpman's leggings and cape-just a pair of walking boots, and if it's cold, an Everton FC scarf and wool hat.

He crisscrossed, and exposed charities in the British Isles came rain, shining or snowing. His most extreme challenge was walking between England's highest mountains in mid-winter Scotland.

He marveled at the top of Ben Nevis.

"So what happens when I put on speed. I get a completely different mindset. I'm determined not to wear clothes all day."

In the photos, Speedo Mick often pulls a tough bodybuilder for the camera. But that brave man is part of the character.

Sitting in the drill room, the actors are preparing for the musical, which tells his story, with Cullen, 60, dressed in a soft and sensitive dress.

Although he never took a formal swimming class until he booked a support boat, he first took the Speedos Swimming English Channel in 2014.

"What I encountered was a miracle because I was training with a pair of Speedos," he joked. "They were faster than me, better swimmers than me, and their skills were much better than mine.

"But I have something they have never had before, and that was a determination..." he delayed. “I’m just a little emotional…a determination and a willingness to accomplish something of this scale.”

Coulun believes that this determination comes from “my negativity comes from the same place in my negative emotions.”

During his childhood in Liverpool, he suffered “a lot of turmoil”, used and abused his teenage drinks and drugs, and became homeless.

"I'm just lost everything to be honest," he said. "It was a sad life. It was horrible and the torture was painful, I did it to myself. But I couldn't stop."

He finally got clean in 2001 and was determined to turn the negative emotions of his life into something positive.

"It used to be a long time, but now it pushes me forward. That's my engine. I've suffered a long time and now I just don't want to do that anymore."

After a shoulder injury that defies expectations and a shoulder injury, Coulun “hopes the world knows that this has happened.”

So he ordered a pair of blue trunks, followed by the name of his beloved football team and "after all the games, 'Everton' carved 'Everton' on my ass.

"The fans are so generous," he said. "I could have been torn to pieces at any time. But, they all applauded and passed the money, put it in my bucket, put it in my panties. You don't have a lot of other places to put it!"

He has very little magic and has also begun raising smiles and funds in away games.

"I have a front seat, with all the generosity, all the kindness and all the love that can be given," Coulon said.

"There are a lot of negative emotions in the world and I just see all of this positivity. It has had a huge impact on me and everyone else."

Looking for new challenges, more money and greater reactions, Cullen took a series of increasingly ambitious charity walks - to Wembley and Lyon's Everton races, and then 1,000 miles from John O'Groats to Land's finish.

In 2021, he conducted five months and 2,000 miles of operations between London, Edinburgh, Cardiff, Dublin and Belfast. Before climbing Ben Nevis, Snowden and Scarver Parker.

However, onlookers don’t always welcome the sight of a middle-aged man in a light swimsuit.

He added: “There are some negative things too.”

“I spit and was pushed to the floor and threw it on me, throwing a pint away, and I was thrown away several bars after trying to get in for some food.

"It's fun because I haven't had a drink for 16 years and I'm still thrown away."

Speedo Mick's 2023 Walk has raised over £1 million in support of mental health, disadvantaged young people and homeless charities.

But this was his last major outing. "I know I only have a certain timeline to keep doing this at my pace. When you're 80, you can't do that."

Despite their similar tastes in lingerie, Speedo Mick is not Superman.

Coulen acknowledged that the hard challenges had caused a huge loss and “had a huge harmful effect on my mental health and my personal relationships.”

He said. “After the last guy, I reached the ground at 1,000 mph and ended up in the clinic because I had a big breakdown.

"Looking back, I didn't manage myself. It felt like I paid a huge price to do all of these things. Too much for me. That's too much."

The stage performance will open at the Liverpool Royal Court Theatre on Tuesday, making Karen a new focus.

On the surface, it was a "all-hero" who "taken on many important life affirmations, accomplished their work, and raised a lot of money", and he was Boff Whalley of the rock group Chumbawamba, who wrote music.

“But the real story is why he wants to do it, at what cost he does it.

“It’s like, ‘He’s like you, he has problems, he’s struggling with addiction and mental health issues, and that’s how he finds the way through these.”

John Fay, the author of the show, agreed. "He's a very inspiring and charming person. He can walk into a room and make people smile. The guy's endurance and what he's accomplished seem to be superhuman.

"But the most important part about him is that he is very human. He has his own vulnerability. He is like everyone else in the world."

Liverpool actor Paul Duckworth plays the title role and says Speedo Mick is a "local legend".

"We all have our complexity and vulnerability. He is a very considerate and very sensitive person."

In addition to trying to capture Curlun’s character, Duckworth must stand out.

The actor said with a creepy expression, “There is only a moment (in the show) to put on a T-shirt because most of his achievements are done in his Speedos.” “Nowhere to hide.

"It was shocking when I put them in the other day. Michael was the only one who saw me. In Mick's words, 'You have to have shorts. You have to have speedos, companion.' I'm trying to get that mentality."

The show is a story of a quirky, tolerant but error-prone character, though Coulon has some reservations about putting it on stage.

“I’m a little anxious about the fact that I’m making myself vulnerable again because I’m telling everyone about my personal life,” he said. “They’re going to see a completely different side here.”

However, he hopes the show will start conversations about addiction, mental health, overcoming challenges and healing.

“But the biggest message that people get from it is that being all of you, everything that happens in life is OK – being you and having hope is OK.

"Get hope from this story because you never know what will happen. I have a drama about my life in the Royal Court Theater and it was a victory. It was amazing."

The musical Speedo Mick is held at the Royal Court in Liverpool from June 3 to July 5.
