Nearly 10 years after her last feature film role, Dolly Parton has signed on to co-star in an upcoming Disney comedy, Frank McKlusky, C.I.

David Sheridan is set to star in the film, playing Dolly's son, an overzealous insurance agent. No word yet on the specifics of the role, but if you know the 55-year-old buxom blonde at all, you know she'll pack some zing in her performance.

Dolly's last big screen appearance was in The Beverly Hillbillies, in which she played herself.
