Diane Lane will be starring in an upcoming Disney film alongside a horse. "Secretariat" will tell the story of the titular character, a 1973 Triple Crown-winning racehorse, and his owner.

The 44-year-old "Unfaithful" actress will play Penny Chenery, known as the "First Lady of Racing" who owns Secretariat. Penny is a mother and housewife who knew little about horse racing when she inherited her father's farm in Virginia.

Secretariat already showed racing prowess even before becoming the 1973 Triple Crown champion, but Penny still considered selling him and everything else after she was hit with a large inheritance tax, Variety reports.

Randall Wallace ("We Were Soldiers") will be directing from the script by Mike Rich.

Production will begin in the fall.
