Barbarella Barbarella (1967)
The Sexy Character: Living in a strange future that sort of looks like a fetish version of the sixties, Barbarella (Jane Fonda) jets off into space after being ordered to retrieve a doctor from a distant planet.
Hottest Detail: Well, she’s got some of the coolest space clobber we’ve ever seen.
And enjoys taking off said clobber in retro-soundtracked montages.
Princess Leia Star Wars (1977-1983)
The Sexy Character: Lover of Han Solo (Harrison Ford), cinnamon buns and kicking a little booty, Leia (Carrie Fisher) may be a princess, but she’s more the ball-busting Mononoke sort than the Disney damsel type.
Hottest Detail: Her tempter? (It’s pretty fiery.)
Oh, alright, the gold bikini.
Jessica 6 Logans Run (1976)
The Sexy Character: A resident of a future utopia where citizens are only permitted to live until they’re 30, Jessica 6 (Jenny Agutter) gets swept up in an escape plot with soon-to-be-recycled Logan 5 (Michael York).
Hottest Detail: She’s less showy than Farrah Fawcett’s cosmetics-obsessed Holly 13, meaning she’s like a really hot girl next door.
That is, a hot girl next door who doesn't seem to own any underwear.
Lisa Weird Science (1985)
The Sexy Character: The creation of nerds Gary Wallace (Anthony Michael Hall) and Wyatt Donnelly (Ilan Mitchell-Smith), Lisa (Kelly LeBrock) is the perfect woman – a sexy lady with a thing for geeks. Swoon.
Hottest Detail: Though the idea in general is morally dubious (creating a woman for sex? C'mon), Lisa’s first words are pretty damn saucy: “So, what would you little maniacs like to do first?”
Nyota Uhura Star Trek (2009)
The Sexy Character: A whipsmart wise-ass who can hold her own against the guys, Uhura (Zoe Saldana) ends up fighting space baddies alongside Captain Kirk (Chris Pine) and Spock (Zachary Quinto) aboard the starship Enterprise .
Hottest Detail: You’ve seen her Starfleet uniform, right?
Han Solo Star Wars (1977-1983)
The Sexy Character: A hero’s hero, Han Solo (Harrison Ford) doesn’t give a damn about much, except for buddy Chewbacca and the Millennium Falcon.
That’s until Princess Leia comes along, of course.
Hottest Detail: He’s so cool that he remains frosty even in the face of certain death.
For evidence, see the infamous “I know” during Empire Strikes Back ’s carbon freezing scene.
Nancy Archer Attack Of The 50 Foot Woman (1958)
The Sexy Character: Socialite Nancy Archer (Allison Hayes) goes through a somewhat dramatic transformation when she’s struck by a glowing white ball that causes her to grow – yep – to 50 foot tall.
Hottest Detail: Not only is Nancy a 50 foot woman, she’s a 50 foot woman in a mini-skirt .
Don't look up.
Cora Fantastic Voyage (1966)
The Sexy Character: The sexy assistant to Dr Peter Duval (Arthur Kennedy), Cora Peterson (Raquel Welch) goes on a quest through the human body aboard a miniaturised submarine.
Hottest Detail: Ever wondered why sci-fi films love cat suits so much? Blame Raquel Welch for making them look so damn good.
Nova Planet Of The Apes (1968)
The Sexy Character: A girl held captive by the apes, Nova (Linda Harrison) wears only scraps for clothes and has the kind of natural tan that would turn even Jordan green with envy.
Hottest Detail: Nova’s sort of a futuristic cavegirl crossed with that popular girl from school. Primal.
Alex Saturn 3 (1980)
The Sexy Character: Without a doubt the sexiest scientist we’ve ever come across, Alex (Farrah Fawcett) is stationed on a research station on Saturn’s third moon.
Conducting experiments that are vital to Earth’s future, she’s a babe with a brain... and some rather eye-catching shoulder pads.
Hottest Detail: When she’s not wearing this fetching ensemble, she’s wearing nothing at all.
It’s a hard life.
