LA-based Gravity Films has attached Katherine Brooks (pictured) to direct its first film Freak, based on the life of Julie Krone, the only female jockey in the US to win a Triple Crown race.

Casting is underway on the project ahead of a scheduled April start in Michigan and New York. Brooks wrote the screenplay based on Krone’s autobiography Riding For My Life.

Brooks and Gravity Films principal Sophie Watts will produce while John Manulis will serve as executive producer.

Krone achieved close to 4,000 career wins and claimed more than $90m in purse earnings. She also bears the distinction of becoming the only female jockey to be inducted into the National Museum Of Racing and Hall Of Fame.

“Julie is a freak of nature, and although I admire her accomplishments in racing, it is her personal triumphs that drew me to the project,” Brooks said. “I can’t relate to winning a Triple Crown race, but I can relate to fighting for an impossible dream.”

“As an athlete, I have an insurmountable amount of desire,” Krone said. “I’m ruthless, cocky, self-assured, and almost always unbeatable… If the gate is closed, climb the fence.”

Brooks recently directed the drama Waking Madison starring Elisabeth Shue, Sarah Roemer, Taryn Manning, Will Patton and Frances Conroy. Her credits include the feature Loving Annabelle.
