Jodie Foster, 38, has withdrawn "The Dangerous Lives of Altar Boys," which she co-produced and stars in, from next month's Sundance Film Festival, reports Variety. So far there has been no explanation from Foster's Egg Productions as to why the $20 million picture, which features extensive animation, was yanked, though it is believed that the movie simply isn't ready. Foster's last movie was last year's well-dressed period piece "Anna and the King," which failed to ignite at the box office. Based on a 1994 novel by the late Chris Fuhrman, "Dangerous Lives" reportedly stars Foster as a nun in a Southern Catholic school whose students create an off-color comic book. The Sundance slot to have been occupied by "Dangerous Lives" has now been filled by "Invisible Circus," starring Cameron Diaz. Sundance is scheduled to run from Jan. 18-28 in Park City, Utah.
