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.
