The single cover was inspired by a Grandville illustration (as are the others from the album).
The music video was directed by Rudi Dolezal and Hannes Rossacher of DoRo Productions, and like all other Innuendo videos the video was filmed in February 1991 at Limehouse Studios. Costumes were created by Diana Moseley. It features the band dressed and acting in an absurd andsurreal manner, including guitarist Brian May dressed as a penguin (a reprise of his outfit featured in the booklet of the first Queen album), drummer Roger Taylor wearing a tea kettle on his head and riding a tricycle while Mercury sneaks up on him and ischasing him, a man in a gorilla suit (rumored to be Elton John), bassist John Deacon as a jester, and Mercury wearing a bunch of bananas as a wig, which corresponds with the line "I think I'm a banana tree".
"I'm Going Slightly Mad" is the last Queen video to feature significant creative input from Mercury. He was already considerably ill at the time due to AIDS, which would claim his life less than a year later. Despite this, the viewer seesMercury as very mobile and expressive in the scenes of the video. He even actively co-directed some of the video's storyboards. Mercury wore thick make-up to cover up the blotches on his face, and an extra layer of clothing underneath to conceal his weightloss. He also wore a wig, which covered his receding hairline, and a suit, both in the goth-inspired style popular at the time.
