Reynolds reposted the photo of the buddy-buddy actors, sharing his support for Jackman and co-star Taron Egerton's respective roles in the film Eddie The Eagle.

"Saw EDDIE THE EAGLE tonight! Probably the best underdog film I've ever seen. @thehughjackman and #taeonegerton were BRILLIANT," Reynolds wrote on Instagram.

The pair are known to have an ongoing, banter-filled friendship, with Reynolds often imitating Jackman's Australian accent.

Jackman, who is nearing the end of his iconic run as Wolverine, posted a video of Reynolds on his Instagram account, where he pretends to be Jackman.

"G'day mate," the video starts."Hugh Jackman here, just reminding you to get your votes in for People's Sexiest Man Alive," Reynold said in a charmingly bad Aussie accent.

Reynolds also took a dig at the iconic Aussie actor in a special Australia Day video, where he sends a message dressed as Marvel anti-hero Deadpool.

"Only one teeny problem, you gave us Wolverine and for that, I can't forgive you.

"I've got no problem with Hugh he's a delightful guy, he really is a true legend."

"But the movie, that was a career low for me. You'll understand."
