Oliver Warbucks is the daunting millionaire who made his fortune during World War I as an industrialist. This is a challenging role, so cast an actor that can appear middle-aged, self-assured and confident. In the beginning, Warbucks is awkwardly affectionate toward Annie and then finds himself completely charmed by her. Cast an actor who is focused and gently authoritative. His few solos in "N.Y.C." are secondary to the character commitment as an actor.
