EXCLUSIVE: Less than a week after filming of the HBO Films movie Phil Spector was suspended after co-star Bette Midler had to pull out for medical reasons, the producers of the David Mamet-written and directed movie have found a replacement. And boy did they deliver. Oscar winner Helen Mirren has been tapped to star opposite Al Pacino in the film, which explores the client-attorney relationship between legendary music producer Phil Spector (Pacino) and defense attorney Linda Kenney Baden (Mirren), who represented Spector during his first trial for murder. Mamet, Barry Levinson and Pacino are executive producing Phil Spector, which had done 6 days of shooting when it suspended production last Tuesday after Midler suffered from a herniated disk. Filming is now expected to resume next week. In addition to her Academy Award for The Queen, Mirren has won 4 Emmy Awards, including one for the HBO miniseries Elizabeth I.
