"Ella Enchanted" writer Laurie Craig is writing the screenplay inspired by the Newberry Award-honored books about a lively -- often misunderstood -- little girl named Ramona Quimby, who thrives on attention and loves to make noise.
Actress and filmmaker Sarah Polley previously played the character on the 10-part Canadian series, "Ramona," in 1988.
Allen, who is best-known for directing "Aquamarine," is also attached to direct "My Mother's Boyfriend," a dark comedy produced by Chris and Paul Weitz's Depth of Field company.
The director recently sold her first novel, "My 40 Hot Sisters," to the New York publishing company, Alloy Entertainment. It is expected to hit stores next year.
