The Twilight Zone (1959 TV series) season 4
Season of television series
The fourth season of The Twilight Zone aired Thursdays at 9:00–10:00 pm on CBS from January 3 to May 23, 1963.
This season broke with the previous seasons in presenting hour-long episodes instead of the earlier half-hour episodes. The opening sequence was revamped, and introduces the now-iconic floating door, smashed window, clock, eyeball, wooden doll, and the equation for Einstein's theory of relativity. Rod Serling's narration was also changed from the earlier seasons as well:
"You unlock this door with the key of imagination. Beyond it is another dimension. A dimension of sound. A dimension of sight. A dimension of mind. You're moving into a land of both shadow and substance, of things and ideas. You've just crossed over into the Twilight Zone."[1]
An intermission graphic based on this opening was used for the fourth and fifth seasons as well.[2]
