Enrolled in Claremont Men's College

After high school graduation, Williams enrolled at Claremont Men's College in Claremont, California, to study political science; he dropped out to pursue acting. Williams studied theatre for three years at the College of Marin, a community college in Kentfield, California. According to the College of Marin's drama professor James Dunn, the depth of the young actor's talent became evident when he was cast in the musical Oliver! as Fagin. Williams often improvised during his time in the drama program, leaving cast members in hysterics. Dunn called his wife after one late rehearsal to tell her that Williams "was going to be something special".
