Vienna  - A Vienna theatre artist announced details Monday of an upcoming production centred on the case of Josef Fritzl, the Austrian who imprisoned and raped his daughter over 24 years.

Hubsi Kramar said he wanted to offer a satirical critique of Austrian society in the piece, calling it a "cellar soap opera" and showing "everything you ever wanted to know about the Fritzls."

"You can't go any lower," Kramar said on his homepage of the satirical play entitled Guesthouse Fritzl, which will run in Vienna's 3raum-anatomietheater from February 23, .

The play would not exploit the Fritzl case, said the theatre's publicist Gabriele Mueller-Klomfar, but would "criticize a society in which something like this is possible."

The production is planned to run parallel to Josef Fritzl's trial, due to start in March. Characters include not only Fritzl and his family members, but also a "Fritzlstein monster."

With Guesthouse Fritzl, Kramar stays true to his image as enfant terrible of Vienna's theatre scene.

After the right-wing Freedom Party joined Austria's government in 2000, he visited Vienna's prestigious Opera Ball dressed up as Adolf Hitler.

Josef Fritzl, 73, stands accused of imprisoning and raping his daughter, Elisabeth Fritzl, 42, for 24 years in a basement dungeon until her ordeal ended last April.

Josef Fritzl is also charged with murder, as one of the seven children his daughter gave birth to in the dungeon beneath his house died shortly afterwards. dpa
