This is how it went on a snowy Saturday at the Stampede Corral during the Calgary Comic and Entertainment Expo.Actress Christina Ricci talked about the perils of finding fame too early and losing herself in the dark drama Prozac Nation.Robocop’s Peter Weller bellowed out lectures on Da Vinci, Donatello and the evils of deregulation.And the kids from Shazam!? They offered a goofy crossover idea.“Freddy Freeman becomes Aquaman’s protege, Aqualad,” said Jack Dylan Grazer, who plays Billy Batson’s adoptive brother and nerdy best friend, Freddy Freeman, in the blockbuster. “I get to wear a speedo and ride on a Sea-doo and I have a little nerf gun.”“All of that is a lie,” he quickly added. “None of that is happening.”Grazer was joined by Asher Angel, who plays the young orphan boy Billy Baston who is bestowed adulthood and superpowers when he transforms into Shazam (Zachary Levi).They were on hand, alongside Levi who joined them later, to represent the box-office hit, which has become one of the year’s top-grossing movies and among the first DC Extended Universe films to eschew the dark, angsty tones of Batman and the Justice League in favour of light, family-friendly fun.The tone of the all-too-brief panel Saturday afternoon — it lasted roughly 25 minutes — was cheerfully juvenile, with Angel and Grazer repeating the idea that playing an overgrown child is definitely in Levi’s wheelhouse.“In all seriousness, he’s acting, he’s doing his job, he’s playing his character,” said Glazer. “But in reality, he is actually like a huge kid. He’s a big boy, big hairy man-child with an accentuated adam’s apple and triceps and things. So that’s the off-putting part.”The two were eventually joined by Levi, who had already participating in a panel earlier that day, and the three answered obligatory questions from the audience about what superpowers they would choose and their favourite scenes.For the uninitiated, in the movie Shazam receives the wisdom of Solomon, the strength of Hercules, the power of Zeus, the course of Achilles and the speed/ability to fly.“All of Shazam’s powers, I would take the wisdom of Solomon,” Levi said. “Because I think it’s dope, but also because if I had the wisdom of Solomon I could build a super-suit that would give me all the other powers. I’d be like the wisest Tony Stark ever. It would be amazing.”“I would have the strength of Hercules,” said Angel. “Let me tell you why. So I could take Zachary in a fight, that’s why.”“We’re the same guy!” Levi said.The only time the panel became even slightly serious was when an audience member asked about the themes of family in the film.“Getting to work with all these kids was fantastic,” Levi said. “They were literally doing field trips in Toronto all the time . . . never invited me. That’s fine. I was busy, I was working, I was being Shazam. Off-camera it was very, very familial. Perhaps that’s what you got to see on screen, that connective tissue.”“What he’s trying to say is: We became a real family but he wasn’t included,” Angel said.The Calgary Comic and Entertainment Expo runs until Sunday at Stampede Park.
