A strange thing happened in 1995, when Kilmer took over the role of Bruce Wayne for Batman Forever. Once one of Hollywood's most gifted young actors, the guy who earned our movie-watching trust in The Doors showed that he could easily become a non-presence. His Bruce Wayne proved to be a dud, beginning a now-16-year-streak of uninspired performances, save for 2003's Wonderland and 2007's rock-solid little surprise The Salton Sea. His recent film camaraderie with 50 Cent makes sense; finally, he's found someone with less ability and even less shame than himself.
