When Carson falls into Kei's bath, he inadvertantly(?) places his hands on her exposed breasts. Though she admonishes him, he softly squeezes them as he tries to explain his actiona.

The opening credits sequence consists of James Bond-esque, psychedelic images of nude women in silhouette. Their nipples are visible.

Kei and Yuri spend a large portion of the film in bikinis makeshifted from towels. Similarly, Carson spends much of the film in his boxers.

In a scene where Kei, Yuri and Carson are trying not to fall, Carson keeps Yuri from falling by quickly grabbing her makeshift bikini bottom, exposing her entire bare butt for multiple shots.

Kei and Carson go through some significant sexual tension throughout the film.

Some extended action sequences, some of which feature alien beings getting slashed and crushed with green, slimy viscera splattering everywhere.

"Damn", "hell", "bastard", "ass" and "son of a bitch" are used throughout each the original Japanese, the ADV Films dub and the Streamline Pictures dub to varying degrees.

The Streamline dub adds some scathing insults to Carson's dialogue.

The scenes of alien violence and carnage may be too intense for children
