There he began devoting his time to the theater group the Washington Street Players. After spending time at the American Academy of Arts in Los Angeles, Shields starred in productions of Shakespeare's "A Midsummer Night's Dream" and "Hamlet."

Shields starred in the independent film "Crime and Punishment in Suburbia" and the Freddie Prinze, Jr. comedy "Boys and Girls."
