Mark Ruffalo Joins 'Eternal Sunshine' Cast

Eternal Sunshine of the Spotless Mind

Mark RuffaloMark Ruffalo ("Windtalkers") is in final negotiations to join Jim Carrey, Kate Winslet and Kirsten Dunst in "Eternal Sunshine of the Spotless Mind," an offbeat comedy scheduled to go before cameras in mid-January in Gotham, reports Variety.

Michel Gondry ("Human Nature") directs the Focus Features project from a script by Charlie Kaufman.

Like Kaufman's "Being John Malkovich," much of "Sunshine" takes place in the recesses of the human brain. The story concerns a man who tries to erase a particularly steamy relationship he had with an ex-mate. Ruffalo will play a lab technician involved in the memory-erasing procedure.
