Amber Tamblyn, whose The Grudge 2 opens this weekend - and whom I hope to Q&A later today, hint-hint to her publicist who may be reading - has joined Blackout, an indie thriller about three people trapped in a hospital elevator for almost 24 hours.... Also per the Hollywood Reporter: Randy Quaid is in talks to play the mentor of Gary the Tennis Coach, starring Seann William Scott.... Brit actor Paddy Considine will play a London journalist sniffing around the CIA in The Bourne Ultimatum, now filming in Europe and Africa.
