“Star Trek is a cult, and any time you’ve got a cult, it continues and continues,” Woodward said. “They’re getting ready to do another Star Trek movie now and some of the original people could be in it. It just keeps going. So, no, it doesn’t surprise me. It doesn’t surprise me, not at all. The (conventions and autograph) shows that I’ve gone to, most of the people want me to sign pictures from Star Trek. I sign pictures from Dallas and the westerns and Cool Hand Luke, too. The Man with No Eyes from Cool Hand Luke is still very, very popular, and that’s almost 50 years, too. But it’s mostly Star Trek that people want me to sign pictures of, and I get that.”

According to the Fort Worth Star-Telegram, Woodward was born in Fort Worth in 1925. He graduated from North Texas Agriculture College in 1948. The college named Woodward a distinguished alumni in 1969.
