"This is a fictional encounter between Geert Wilders and Anders Behring Breivik," Olivier Willemsen, spokesman for the cultural centre "Die Balie" told AFP.

"Behring Breivik asks Wilders the big question: 'How far are you willing to go for your ideas?'" Willemsen said of the play, which will premiere on March 22nd and run twice on March 25th.

In the work by Dutch playwright Theodor Holman, Wilders and Behring Breivik have a chance encounter at Heathrow airport after the British screening of Wilders' real-life anti-Islam film "Fitna" ("Discord" in Arabic).

Released in 2008, "Fitna" showed shocking images of 9/11 and other terror attacks on Western targets interspersed with verses from the Koran.

The movie caused widespread outrage in Muslim countries, as well as opposition from the Dutch government, which feared it might spark a militant response similar to that which followed the publication in Denmark of cartoons depicting the Muslim prophet Muhammad.

On July 22nd, Behring Breivik, who has claimed to be on a crusade against multi-culturalism and the "Muslim invasion" of Europe, set off a car bomb outside government buildings in Oslo, killing eight people.

He then went to Utøya island, some 40 kilometres north-west of Oslo, and, dressed as a police officer, spent more than an hour methodically shooting and killing another 69 people, mainly teens attending a summer camp hosted by the ruling Labour Party's youth wing.

Wilders strongly condemned Behring Breivik's attacks and said he was disgusted by the Norwegian's mention of him in his 1,500-page manifesto that circulated on the internet shortly beforehand.

The Dutch politician's Freedom Party has 24 seats in the 150-seat parliament, where it lends its support to the coalition government of Dutch Premier Mark Rutte.

A theatre in Copenhagen sparked controversy in January by announcing it would produce a monologue based on Behring Breivik's manifesto.
