Is dennis weaver sigourney weaver's father?

No. Sigourney Weaver was the daughter of English actress Elizabeth Inglis and former NBC president Sylvester (Pat) Weaver.

Dennis Weaver only have three sons: Rick Weaver, Robert Weaver and Rusty Weaver.

Despite a privileged childhood, Sigourney Weaver's formative years weren't always easy. She lacked confidence in her own beauty, a trait brought on by the fact that she was generally taller than most girls she knew and by her mom, who told her at the age of 8 that she was simply "plain" looking.

Though self-conscious about her height and looks, Weaver acted in off-Broadway shows, and had her big break in the 1979 film Alien. Weaver appeared in many films throughout the next three decades, including Ghost Busters, Working Girl, Aliens and Avatar. Weaver has been nominated for three Academy Awards.

In latest buzz, Sigourney Weaver will receive the 2016 Donostia Award for career achievement at the 64th San Sebastian Festival, which runs Sept. 18-26 at the Basque resort city. Find out more at Variety.com.
