Clarence Gilyard, Jr. 'Die Hard,' 'Walker Texas Ranger' and 'Matlock' star, dies at 66

Actor Clarence Gilyard, Jr., best known for his roles in “Walker, Texas Ranger” and “Die Hard,” died at age 66 at his home in Las Vegas, according to the college he taught and his agent.

"It is with profound sadness that I share this news," said Dean Nancy J. Uscher of the University of Nevada, Las Vegas, where Gilyard taught as a film and theater professor, in a statement Monday.

"His students were deeply inspired by him, as were all who knew him. He had many extraordinary talents and was extremely well-known in the university through his dedication to teaching and his professional accomplishments. He had a national and international following through his celebrated work in the theatre, in film, and television."

A representative for Gilyard confirmed the news to Fox News Digital, noting that the actor hasn’t been in “good health for a few years.”

Gilyard began his over 30-year career in television and famous for his roles in hit series “Matlock” and “Walker, Texas Ranger.”

In the mystery legal drama “Matlock,” he played the role of Ben Matlock’s private investigator, Conrad McMasters, opposite Andy Griffin from 1989 to 1993. Gilyard appeared in almost every episode starting in season 3 – 85 episodes in all.

Afterward, he began another long-time co-starring role opposite Chuck Norris on crime drama “Walker, Texas Ranger” as James “Jimmy” Trivette from 1993 to 2001.

But before those TV roles, Gilyard was cast in supporting roles in now-classic films – 1986’s “Top Gun” as a naval flight officer and 1988’s “Die Hard” as the villain’s tech expert.

"His generosity of spirit was boundless - he was always ready to contribute to projects and performances however possible. We remember Clarence with joy and gratitude for all he contributed to the College of Fine Arts, the UNLV community, and, through his impressive personal achievements, to the world," Uscher concluded in her statement.
