Like, a horror movie that instead of scare you makes you laugh more than a comedy
A lot of people think Star Wars is science - fiction. But it is fantasy.
Why do you think that? To me it’s a science-fiction film because it seems to happen in the future
Science fiction usually tries to stick to realism to a degree in how it uses futuristic tech and ideas. George Lucas didn’t really try to do that. He always called it a space opera
The Princess Bride. The title does not at all suggest that this is a comedy movie.
Cabin in the Woods, Tucker and Dale vs Evil, and Troll 2
Donny Darko, maybe? All I knew was that it was a psycho thriller. I had to go on the internet to find out WTF I had just seen, because it’s also a sci-fi.
I’m trying to understand this question a bit more. Do you mean intentionally not typical for it’s genre, or unintentionally?
If intentionally, I’d go with Shaun of the Dead, though it’s actually considered part of the ‘comedy horror’ genre so wouldn’t necessarily consider it ‘lying’ about being hilarious film about a zombie apocalypse.
If unintentionally, then hands down Troll 2. You can’t piss on hospitality.

Could consider the Ash vs Evil Dead series to qualify. It was technically horror, but done in a very entertaining and campy (hindsight) way and not taken too seriously.
Deadpool famously advertised itself as a Valentine’s day romcom.
I’ve got one that’s the opposite: Tusk (2014) is listed as a comedy, written and directed by Kevin Smith (of Jay and Silent Bob fame), but is actually a horror film.
Star Wars isn’t a sci-fi at all it’s just an action movie in space. Sci-fi deals with moral dilemmas arising from the use of technology. Star Wars is just a bunch of space lasers.
Stalker by Tarkovsky. The description made it sound like a really cool sci-fi/fantasy, bleak adventure movie. Instead it was just a bunch of melodramatic philosophy. Pretty much nothing even remotely sci-fi happens.
