‘Saved By the Bell’ star, who appeared in ‘The X-Files,’ dies at 89


A 91-year-old actor who appeared as a recurring guest on the television series “The X Files” died Tuesday, CBS News has confirmed.

Fred G. Smith, best known for his role as the character of FBI Special Agent Mulder on the series from 1966 to 1990, died at his home in New York City, the network said.

Smith died after a long battle with cancer.

He had been battling the disease for more than a decade, according to the Associated Press.

Smith was best known as Mulder, but in the series he also played the character David Mulder in episodes titled “Mud and Blood” and “Battleship.”

Smith was also known as the “B.B. King of TV,” according to his credits.

Smith’s last appearance on the show was on February 16, 1993, in “The Ultimate Sacrifice,” where he played Mulder and Scully in a series of “Buffy the Vampire Slayer” episodes.

The show, which ran for eight seasons, concluded in 2001 with a season-seven finale.

Smith said he was in the middle of a retirement when he started filming “TheXFiles” in 1971.

He played Agent Mulders “X” in the show.

Smith had a career that spanned more than 20 years.

He was inducted into the Rock and Roll Hall of Fame in 1978.

He also starred in the animated series “Tales from the Crypt” and in the movie “Porky’s World.”

In 1997, he starred in an episode of “The Twilight Zone,” where his character, William “Billy” Peebles, was a fictional scientist who invented a machine that could detect “dangerous substances” and then killed the scientists.

Smith is survived by his wife, Mary, and two children.

He will be buried at St. Luke’s Cemetery in Santa Fe, New Mexico, the family said.
