Two things have just come out both sourced from Us Magazine.
1) The movie Heath Ledger was working on has officially been shut down. No word on if The Imaginarium of Doctor Parnassus will resume production. Highly unlikely as the cast and crew have been let go.
2) The police "recovered a $20 bill with narcotic residue on it" in the apartment where Heath Ledger's body was found yesterday afternoon. Prescription drugs and "several drug packets containing an unknown substance" were also found and listed on the official police report.
