- "It's already mutated into human form! Shoot it!!!"
- —Sherman Peabody
Sherman Peabody was the son of Old Man Otis Peabody and his wife Elsie, and the brother of Martha. He investigated the barn with his father when the DeLorean time machine crashed into it in 1955. Sherman believed the vehicle to be an alien spaceship after reading a science-fiction comic book called Tales from Space. When Marty McFly exited the DeLorean in the radiation suit, the family ran in fear.
Behind the scenes
- As with his father Otis, Sherman was not referred to by name in the film, but was identified in the credits.
- The name was a reference to "Peabody's Improbable History", a feature on the cartoon The Rocky and Bullwinkle Show. In a reverse of the "boy and his dog" story, Mr. Peabody was a dog who had invented the "WABAC", a time machine, and Sherman was his boy, a young man who accompanied him on his travels through history. The show, which made its debut in 1959, was a favorite of both Bob Gale and Robert Zemeckis.
