Sally Kirkland -- Emergency Surgery After Theater Fall

Academy Award-nominated actress Sally Kirkland was rushed to the hospital Sunday night after taking a nasty spill at an L.A. film festival -- breaking her leg in two places.

Kirkland was on her way to the stage at the Studio City Film Festival to receive her award for Best Actress in a Dramatic Short when she fell to the ground, also dislocating her ankle during the accident.

A rep for the actress says Kirkland blames the fall on poor lighting in the theater.

An ambulance arrived shortly after the accident and rushed her to a nearby hospital. On Monday, Sally underwent emergency surgery to repair the breaks with a metal plate and screws.

We're told Sally remains under doctor's supervision.

A rep for Sally tells TMZ, "Currently suffering from extreme pain, Sally remains hospitalized following a successful surgery to repair the injuries resulting from her fall. Despite the circumstances, Sally is in good spirits and is optimistic about her recovery."
