It’s impossible to neatly summarize how important author Richard Matheson was to the word of writing, fantasy and science fiction and movies and TV.

Matheson, who has passed away at age 87, left so many great works behind.

Here are just a few.

“I Am Legend,” which inspired movie treatments starring Vincent Price, Charlton Heston (“The Omega Man”) and Will Smith.

“The Shrinking Man,” adapted as “The Incredible Shrinking Man.”

Other works that were made as movies, some of them written for the screen by Matheson: “What Dreams May Come.” “A Stir of Echoes.”

Original movies and TV shows he wrote: “House of Usher.” “The Raven.” “Comedy of Terrors.”

Several of the best-remembered “Twilight Zone” episodes, including “Nightmare at 20,000 Feet.” The “Star Trek” episode “The Enemy Within.”

“Duel.”

“The Night Stalker” and its sequel, “The Night Strangler.”

“The Legend of Hell House.” “Trilogy of Terror.” “Somewhere in Time.” “Twilight Zone: The Movie.”

“Jaws 3-D.”

“Profile in Silver,” the great JFK assassination time travel story for the 1980s remake of “The Twilight Zone.”

“Steel,” the story that was the basis for the Hugh Jackman fighting robot movie “Real Steel.”

Matheson might have been the most versatile and most accomplished writer to ever move between books, short stories, TV and movies.

He will be missed, but his legacy lives on.
