Like many character actors, Glenn Morshower may not be immediately familiar to film and television audiences. But his astonishingly wide body of work in both mediums served as proof positive of his durability and versatility in the industry. The Dallas native began his screen career as a high school student in the regionally lensed comedy "Drive-In" (1976), and soon moved into steady work as a bit player in Hollywood. As he grew from juvenile to mature roles, Morshower transitioned from relative innocents to more physically imposing men of authority, playing a host of law and military officials in countless features and television shows. By the late '90s, he was a familiar face on both the silver and small screen thanks to appearances in "Air Force One" (1997), "Pearl Harbor" (2001), "CSI: Crime Scene Investigation" (CBS, 2000-15) and "24" (Fox, 2001-10). Along the way, he forged significant relationships with the "Star Trek" franchise, appearing in "Star Trek: Generations" (1994) and three spin-offs of the original series, as well with the director Michael Bay, who cast him in three of the "Transformer" features. That Morshower was still in demand after four decades in the business was an undeniable testimony to his status as one of the most popular supporting players in screen entertainment.
