Actor Josh Brolin and director Michael Mann are among those paying tribute to Val Kilmer, who died Tuesday at age 65.

Michael Mann, Francis Ford Coppola, Nicolas Cage, Jim Carrey and Josh Brolin were among the many entertainment industry figures who paid tribute to Val Kilmer after news of his death was announced.

Nicolas Cage, who starred alongside Kilmer in 2009's "Bad Lieutenant: Port of Call New Orleans," shared a statement with "Good Morning America" on Wednesday, paying tribute to his former co-star. "I always liked Val and am sad to hear of his passing. I thought he was a genius actor," Cage said.

Val Kilmer had a face that belonged in movies. A stunningly beautiful heartthrob known for his chiseled jaw and shock of blonde hair that looked great either messy or perfectly coiffed, Kilmer practically glowed whenever he was onscreen, as if he was put on Earth by God himself for the purpose of getting immortalized on film.

Unlike Iceman, Doc Holliday was a character Kilmer found to be very well written in the 1993 Western “Tombstone.” Holliday is dying of tuberculosis in George P. Cosmatos’ film when he meets up with his old friend Wyatt Earp (Kurt Russell) in a classic showdown of outlaws and lawmen (even those attempting to retire).
