Beloved film director Michel Gondry is working on a suitably odd film with his regular collaborator Bjork.
Earlier this year, the pair announced that they were set to reunite for a mysterious project that was described by Gondry as “very undefined… hard to give more precision.”

That project has become a little more defined during an interview with Gondry at the 2010 SXSW Film Festival. Though he was supposed to be promoting his new family focused documentary, A Thorn In The Heart, the French director also dropped a few tantalising hints about the upcoming Bjork collaboration.

“We have a very ambitious project, a sort of scientific musical,” Gondry explained. ”[It’s a movie], but maybe more for museums. Like a 40 minute IMAX project in 3D.”

Björk and Gondry have collaborated together on seven ground-breaking music videos since 1993, but a 3D IMAX musical would be sure to eclipse those short promo clips.

The news is of course an interesting flip on earlier reports this week that fellow sonic explorers Cosmic Gate would be getting into the 3D spirit, remixing the theme from James Cameron’s Avatar epic.

Gondry also has an animated project titled Megalomania and still gestating The Green Hornet starring Seth Rogen, Cameron Diaz and Christoph Waltz to keep him busy, so there’s no word on when he and Bjork will begin filming their ‘scientific musical’.
