Stellan Skarsgård will make an appearance on the cult series "Entourage". According to himself he will play a crazy director for three episodes. Skarsgård is now in Los Angeles starring in Da Vinci Code sequel movie Angels & Demons. When there was a small break in the production he said yes to a guest appearance on Entourage. It was damn fun, he says to TT Spektra.
