Every Sean Connery movie! Imagine a Scottish accent playing a Spaniard from ancient Egypt as an Australian! There can be only one!

Thought the post said Austrian. I need someone to give me a movie that would be better if the cast was Austrian now

The Last Samurai

Sweary Aussie Drama

Captain America: Winter Soldier.

(As much for the Russian characters as the American ones)

The Dark Crystal.

Any Bollywood movie :-)

Matrix.

"That's not a spoon... this is a spoon!"

Crocodile Dundee. Only Paul Hogan doesn't have an Australian accent.

The first rule of fight club is you don't bloody talk about fight club!

Crocodile Dundee

It's suddenly a movie about a weirdly elitist Australian talking down to a bunch of Australian expats.

Blazing Saddles.

The King's Speech.

Although the Yes movie would be good too, just so it could be renamed "Yeah Nah Yeah".

Up (or, as they'd call it, Down).

Shrek

But keep the same voice actors

V for Vendetta.

My answer for these kinds of questions is honestly always just the last movie I saw, because that's always the only movie I can remember.
Well, I watched The Babadook last night and that one would be really funny if everyone were Austraian

Sorcerer's Stone.

"It's leviOsa, not leviosar, you bloody cunt!"

Muppets Christmas Carol

12 Angry Men

No Country For Old Men

With Eric Bana playing Anton Chigur

Braveheart

Star Wars Episode I: The Phantom Menace

No, I will not elaborate. But you can see it.

Crocodile Dundee, all of them. Make Paul hogan the least bogan of the cast.

Blade Runner

Superman might be cool if only because it'd finally be something "different" but not "edgier".

Gone with the Wind

2001
