But yesterday Sacha Baron Cohen took things one step further when he arrived in Sydney airport following a long-haul flight from Los Angeles in character as The Dictator's General Aladeen.
The 40-year-old actor stepped off his flight sporting a full beard, sunglasses, and Qantas pyjamas - which he had customised to include gold shoulder pads and a neck pillow made out of the Australian flag.
Cohen completed the effect by arriving with a bevy of beauties, all wearing matching khaki outfits, in tow.
After arriving Down Under, Cohen was quick to get involved in local politics, joking that he was in the country to search for House of Representatives Speaker Peter Slipper, who is currently under fire amidst fraud allegations.
Speaking to the assembled press, he shouted: 'I have come to meet Slippery Pete. The Slipper is great. What is his number? I need to hire him.'
Meanwhile, the latest trailer for the film focuses on the part of the story which finds the title character struggling in New York after he is kidnapped, has his beard shaved off and is let loose into the city.
Even though he was on the other side of the world, the comedian also managed to cause controversy in the UK earlier this week with the release of a video clip featuring his alter-ego, General Aladeen, the fictional ruler of the Republic of Wadiya, as he congratulated Queen Elizabeth for her reign as a 'dictatoress'.
He says: 'I would like to congratulate your dictatoress Elizabeth on her blood diamond jubilee and I hope it is a smooth transition when her son Charles eventually kills her and seizes power.'
The Dictator also co-stars Oscar-winner Ben Kingsley and Jason Mantzoukas.
The book that the film's screenplay is loosely based on is an allegorical romance novel published anonymously in 2000.
The CIA believes it was written by ghost-writers with the direct influence of Hussein and the simple plot is laden with hidden meanings.
This isn't the first time Baron Cohen has grabbed the headlines in character as General Aladeen, he used the Oscars in February to pull off yet another audacious publicity coup to promote the film.
Initially banned by the Academy from pulling such a stunt, bosses finally relented and allowed the British comedian to take to the carpet dressed in character, who promptly tipped an urn containing 'the ashes of Kim Jong II' over a furious Ryan Seacrest.
The mixture, which turned out to be Bisquik pancake mix, coated Seacrest quite liberally, and he didn't see the funny side.
Cohen undeterred and no doubt happy his stunt had worked wonderfully, added: 'Now when people ask what you're wearing, you will say Kim Jong-Il!'
