The Science of Sleep: According to The Hollywood Reporter, The Motorcycle Diaries star Gael Garcia Bernal is revving up for Michel Gondry's new project, The Science of Sleep.

Bernal, who is generating buzz for his role as Ernesto "Che" Guevara de la Serna in the Focus Features release, has signed on for Gondry's "Sleep" alongside Charlotte Gainsbourg and Alain Chabat.

Preproduction is under way, with shooting pegged to start by year's end in France.

Gondry penned the script, which is being revised. The logline is being kept under wraps because of the changes in the script, but it is known to switch back and forth from dreamlike sequences to reality.
