The Simpsons intro styleguide outlines key points for the show's opening such as using a 1920 x 1080 resolution, 24 frames per second runtime of over 60 seconds, featuring the theme song and yellow colored font. It also provides themes that can be used for episodes such as science fiction with aliens traveling in a UFO through space and burning the title with a laser, and Halloween themes with a spooky laugh and the O in Simpsons fading into a jack-o-lantern.
