My favorite SF comedy is Dark Star.

John Dies at the End.

It’s sci fi/comedy. Best watched whilst high, but good regardless.

Kung Pao is one of the dumbest and most underrated comedies. It's not exactly sci-fi, but it does have aliens and intelligent cows.

I watched it over ten times, and I don't regret a second.

Predestination

It's difficult to know what is less known these days as film recommendation posts happen a lot.

If you told us what you liked we could probably come up with recommendations that let you drill down a bit further.

However:

SF:

• Timecrimes (2007) - if you like Primer or Triangle
• About Time - makes me cry every time

Comedy - I'm rather partial to a kung-fu comedy:

• Close Encounters of the Spooky Kind
• Mr Vampire
• Kung-fu Hustle

SF: Europa Report

I feel weird recommending this movie because I fully acknowledge it's not exactly good, but...

The Man Who Knew Too Little (1997)

This has long been one of my all time favorite comedies. I've seen it probably a half dozen times, and it still makes me laugh out loud. Bill Murray is brilliant and Alfred Molina is clearly having the time of his life. I absolutely love it.

The Game, with Michael Douglas.

The Voices with Ryan Reynolds.

It's a comedy drama following a schizophrenic trying to live a normal life.

It hits pretty hard at times.

Big ole list I’ve been curating off and on. The pad will only last 60 days so move it over to somewhere you won’t lose it

3 Women, Robert Altman.

Paths of Glory, Stanley Kubrick.

Seven Beauties, Lina Wertmueller.

Wings of Desire, Wim Wenders.

Fitzcaraldo, Werner Herzog.

Best Polish SF movie is a comedy from the 80s abut two guys who are hibernated and wake up in a world without men. It was filmed during communism and it's full of hidden jabs at the system. It's actually a good SF movie.

A favorite comedy that i haven't heard mention of in a while: Modern Love, from 1981. Just go in blind.

Knight and Day with Tom Cruise : very under rated movie a lot never saw this movie

The Saint with Val Kilmer also a great flick

The Replacements with Keanu Reeves

What does SF mean?

99 Francs

It's a hilarious french comedy I keep going back to every couple of years.

Dinner in America (2020) I liked a lot
