Mel Gibson showed off his physique and bulging biceps while working out at a Scottish gym before going big at a live event in the city of Glasgow.

The 66-year-old Braveheart star also recalled earlier in the day that it had been 28 years since he last visited Scotland and said he “doesn’t remember much” of his visit to Glasgow, where he decided on his VIP dinner date.

Mel had an experience at the DoubleTree by Hilton Hotel in Glasgow, where spectators paid more than £100 for tickets, plus £300 for a photo session with a Hollywood star, and he popped up at the Daily Athlete gym.

Mel also had his iPhone in hand, which had the settings on the Stopwatch app indicating that he had been timing his rep.

On Sunday night, he took center stage at the Live Experience, a lavish evening of celebrity interviews in a room full of fans.

The movie icon worked with the company at an event in London last year, which was attended by others including Sylvester Stallone, Al Pacino and Arnold Schwarzenegger.

Gibson’s last visit to Glasgow was for the premiere of the historical drama Braveheart, which he directed and starred as the 13th century warrior Sir William Wallis.

Joking about his fear of coming back, the recovering alcoholic actor previously told the Daily Mail: “I haven’t been back since then because I was scared.

“I’ll never wake up for one thing and have to run around in a skirt. . . it’s cold in there!

Appearing on stage in Glasgow on Sunday night, Mayer gave his take on Johnny Depp’s $100 million libel trial against Amber Heard – and appeared to be on the side of his actor friend.

When asked who he was supporting, Mel responded to the cheers from the audience: “I think that’s the answer. That’s what I heard anyway.

Mel also revealed in a live chat with Mel Gibson at the DoubleTree by Hilton that he rejected Batman three times after getting the Batman suit.

After Roger Moore, he also rejected James Bond because he was only 26 and felt he was too young, Timothy Dalton for the role, and the films Rain Man, Gladiator and The Patriot.

Mel later teased viewers that he was interested in seeing his four-hour Braveheart filmed in Scotland and Ireland being “slapped together”.

The star arrived in Scotland on a private jet on Friday ahead of his special event, which charges a £100 ticket and the chance to meet him from an extra £300.
