Simu Liu and Mark Wahlberg brought their bulging biceps to an adoption event and special screening of their upcoming film Arthur the King, which was held at AMC Century City 15 in Los Angeles on Monday.

The Chinese-Canadian 34-year-old and the 52-year-old Dorchester native appeared to have a blast reuniting with Simon Cellan Jones, the director of their dog endurance drama hitting US theaters March 15 and UK theaters March 22.

Mark produced and starred as Michael Light – the captain of an adventure racing team – who befriends a stray wounded dog during a 10-day, 435-mile endurance race through the Dominican Republic.

Wahlberg proudly posed with his canine castmate Ukai, who portrayed the real-life Ecuadorian stray dog that passed away in 2020 from a malignant tumor.

The two-time Oscar nominee wore a grey star-spangled sweater featuring a kangaroo pouch, matching tapered cargo pants, and $180 unlaced Municipal ‘Origin’ sneakers.

Mark – who also sported a light-grey Municipal baseball cap – co-founded the sports utility gear company in 2019 with boxer Gabe Rosado and trainer Mario Guevara.

That same morning, Wahlberg – who boasts 57.1M social media followers – shared a video flaunting his ripped 5ft8in physique while filling an ice bath for his buddy Kenny.

The Family Plan action star frequently starts his days in the gym at 4am in order to keep his arms sinewy, his chest chiseled, and his six-pack abs etched.

Missing from Mark’s side at the screening on Monday was his wife of 14 years, Rhea Durham Wahlberg, and their four children aged 14-20.

Wahlberg will soon begin filming his role as craftsman and professional thief Parker in Shane Black’s thriller Play Dirty to stream on Amazon Prime Video.

The eight-time Emmy nominee also has two other upcoming films – Julian Farino’s spy thriller The Union and Mel Gibson’s thriller Flight Risk.

Meanwhile, Simu slipped his fit 5ft11in form in a black V-neck top beneath a matching zip-up collared jacket, khakis, and black boots selected by stylist Chloe Keiko Takayanagi.

Liu plays Mark’s onscreen teammate Liam in Arthur the King, and art imitated life when he decided to adopt a mutt of his own on the Santo Domingo set in 2021.

The People’s Choice Awards host brought little Chopa along to the screening, and affectionately planted a kiss on the top of her head.

Simu – who boasts 6.5M social media followers – Instastoried a snap from inside the cinema captioned: ‘Going to the premiere of her first movie!’

‘We’ve been tremendously happy,’ the Barbie actor gushed to People last November.

‘I feel challenged and loved and cared for, and I feel championed. I think the best, healthiest relationships are ones where you have each other’s back, and I definitely feel like that’s the case…I definitely see kids in my future. I would be surprised if I was not a father 10 years from now.’

Simu and Wahlberg made sure to pose for a cast and crew shot with Mikael Lindnord, Simon Cellan Jones, Michael Brandt, Ukai, Tucker Tooley, Mark Canton, Dorothy Canton, Tessa Tooley, Cece Valentina, Paul Guilfoyle, and Rob Collins.

Arthur the King was adapted to the silver screen from the 2016 memoir of real-life Swedish adventure racer Mikael Lindnord, who brought his wife Helena and their children Thor and Philippa to the screening.
