Submissions are now open for MoPOP’s 19th Annual Science Fiction + Fantasy Short Film Festival (SFFSFF or “siff-siff”).

Created in collaboration with the Seattle International Film Festival, SFFSFF celebrates out-of-this-world short cinema and the daring filmmakers who make it happen. Films screened at SFFSFF have gone on to be nominated for Academy Awards, featured in museum exhibitions, internationally distributed, and more.

Enter your film today for a chance to see it shine on the big screen at our June 2024 festival!


MoPOP recognizes the importance of representation and accessibility both behind and in front of the camera. We continue to learn and grow every year, working to ensure our festival reflects the vast diversity of science fiction and fantasy creators and fans, especially those who have been historically excluded.

As part of this commitment, we can offer partial and full entry fee waivers to filmmakers who would otherwise be unable to submit their film to the festival, with priority given to creators identifying as BIPOC, LGBTQIA+, disabled, and low income.

Please fill out this short form if you’d like to request a waiver code: Got questions? Contact Maddy Szmidt –

    I feel so fortunate I was able to make it in person. This mighty little one-day fest has built a passionate following of SciFi film lovers with their impeccable programming and vibe curation. Packed house. Huge laughs. Could have lived forever on the viewing experience alone but then our film, Boo Hag or Shadow Man, won the Audience Award and now we're never gonna die! Still vibrating. What. A. Blast.

  • A great honour of having our short film, Backroom Blues, selected to this amazing showcase of genre films. While I couldn't attend in person, a few audience members reached out on social media and told me how great the screening was. Can't wait to submit again in the future.

    I really enjoyed this festival. It was obviously a strange year with having to join in remotely, but it was organised very well. It was very tidy and easy to follow, and the films were all of a great quality. Would definitely recommend entering this festival!
