Look upon Leonardo DiCaprio and witness an actor at the height of his power. Here is a man who escaped the "pretty boy" prison that 'Titanic' nearly imposed upon him and re-emerged as the most exciting actor of the decade, an honest-to-god Movie Star with a knack for not only putting himself in successful films, but for putting himself in brave, exciting, artistically viable films directed by truly great filmmakers.
Although his roles have gotten progressively darker over the years, taking on the role of H.H. Holmes in a film adaptation of the best selling non-fiction book 'Devil in the White City' is a bold step for DiCaprio. He's played his fair share of lowlifes and morally tormented characters, but never a suave, debonair serial killer who builds a torture dungeon on the top floors of his hotel and murders an unknown number people (27 confessed, 9 confirmed but possibly as many as 200) during the 1893 Chicago World's Fair. Say what you want about DiCaprio, but don't say he's unwilling to try new things.
