The Hollywood Reporter gives us an inkling as to why Rachelle Lefevre decided to forgo Eclipse:
Rosamund Pike, Minnie Driver and Rachelle Lefevre are playing Paul Giamatti's many wives in "Barney's Version," the adaptation of the Mordecai Richler novel being directed by Richard Lewis. Robert Lantos is producing via his Serendipity Point Films."Barney's" tells the story of the politically incorrect, fully lived life of the impulsive, irascible and fearlessly blunt Barney Panofsky (Giamatti).
Lefevre will play Clara, Barney's first wife, a wild, troubled artist. Driver plays Barney's second wife, the annoyingly loquacious Mrs. "P." Miriam, Barney's third wife and true love, will be played by Pike.
Principal photography starts Aug. 17 in Rome. Dustin Hoffman also is in the cast, playing Barney's father.
We'll miss you Rachelle!
