Jake Mourns

Jake Gyllenhaal is having a very difficult time dealing with the death of his colleague and best-friend Heath Ledger. Gyllenhaal and Ledger became close pals on the set of their film Brokeback Mountain. Gyllenhaal is also godfather to Ledger's 2-year-old daughter with Michelle Williams, Matilda.

Gyllenhaal has taken time off from the set of his movie Brothers. A source on set says, "He [Gyllenhaal] was there, but he wasn't with us. It was obviously a major trauma ... These guys were very close."
