Actor Ryan Reynolds has taken a swipe at Hugh Jackman in a special Australia Day message while praising Aussies for their "unrelenting condescension towards New Zealand".

In character as Marvel's anti-hero Deadpool, Reynolds claims he "can't forgive" Australians for giving the world the widely panned film X-Men Origins: Wolverine.

"I've got no problem with Hugh (Jackman), I mean he's a delightful guy, true legend. But the movie, that was a career low for me, you understand."

The 2009 Jackman-led Wolverine spin-off was criticised by fans for not staying true to the Deadpool comics.

Wearing Deadpool's red and black suit, with a cork hat, Reynolds mimics an Aussie accent as he wishes locals a Happy Australia Day - "because that's a real thing".

"Seriously, I'd fit right in with your proud nation with its shady criminal past, and it's predilection for black-out drinking and unrelenting condescension towards New Zealand," he says in the video, released ahead of the Deadpool movie premiere in New Zealand on February 11.
