"I Sing the Body Electric" is the 100th episode of the American television anthology series The Twilight Zone. The script was written by Ray Bradbury, and became the basis for his short story of the same name, published in 1969, itself named after a Walt Whitman poem. Although Bradbury contributed several scripts to The Twilight Zone, this was the only one produced. Later, in 1982, the hour-long NBC television movie The Electric Grandmother was also based on the short story. It was also adapted for radio in 2011 in The Twilight Zone Radio Series by Falcon Picture Group.
