Common Sense Note
Parents need to know that this spoof was made as a loving tribute to '50s B-movie sci-fi -- and, as such, has the same squeaky-clean feel and mild peril of those films. There's some sci-fi violence, but since it's being perpetrated by a guy in a rubber suit, it's hard to be too alarmed when men, women, and children are dissolved into goo. Expect a fair amount of pipe smoking (accurate for the era) and some kissing and ogling.
Sexual
Content
Some kissing; some flirty talk between a husband and wife while she's wearing a nighdress. Teens make out but stop to talk about "going all the way"; their dalliance is interrupted by a crashing spaceship. When alien lawman Urp inhabits Dr. Lewis' body, there's some confusion, as Urp is attracted to a woman who's not Dr. Lewis' wife. But it's played as chaste romantic slapstick with some smooching.
Violence
Mostly fairly stylized sci-fi violence; for example, a monster attacks with tentacles, dissolving its victims into brown, foamy goo. Some scuffling and ray gun blasts directed at monsters. A policeman shoots the hero in the shoulder.
Language
Aside from the occasional "hell," minimal.
Social
Behavior
Recreating the style of a '50s sci-fi B movie, the film does have a gentle message about not judging those who are different -- in this case, an alien lawman -- without getting to know them. Departing from '50s standards, the main female character is resourceful rather than weak or passive.
Consumerism
Some mentions of brands like Coke, Rolaids, and Edsel.
Drugs / Tobacco /
Alcohol
Extensive pipe smoking (accurate to the period the movie is set in); a character is presented as a hard-liquor drunk.
