No sex or nudity is involved in this film. However, a suggestive lyric "We made love all day long" is used in a musical number.
Violence & Gore
None
The Blue Meanies hurt each other, and try to hurt Sgt. Pepper's Lonely Hearts Club Band (no specific actors) and the Beatles (no specific actors).
Alcohol, Drugs & Smoking
Mild
The whole movie is basically one big acid trip.
A creature smokes a cigar, which then explodes. There are several drug references (including the film's title), but these should go over the heads of most children.
Frightening & Intense Scenes
Mild
There are many scenes in the movie which may trigger seizures. Epileptics should probably consult a doctor before watching the movie.
The Blue Meanies' appearences may be frightening for younger viewers
