Few actors were able to convey a sense of gravitas like the tall, dignified Peter Graves. Brother of actor James Arness, Graves was readily remembered as one of the hosts on "Biography" (A&E, 1987-2006), where he solemnly intoned about the lives of public figures for over a decade. Prior to "Biography," Graves was a film and television star whose heyday came in the late-1960s with the hip Cold War spy drama, "Mission: Impossible" (CBS, 1966-1973). Before stardom, the actor struggled to make a name for himself by starring in a series of schlock horror films, some of which were lampooned on the cult series, "Mystery Science Theater 3000" (KTMA-Comedy Central-Sci Fi Channel, 1988-1999). Regardless of such inauspicious beginnings, Graves was unafraid to poke fun of his persona, which he did to hilarious effect as the captain of a doomed passenger jet in "Airplane" (1980) and "Airplane II: The Sequel" (1982). Though not known for any award-worthy performances, Graves became engrained in pop culture - both as an understated comedic actor as well as a gifted dramatic performer.
