6 DAYS! 1 EVENT! FEATURES. SHORTS. DOCUMENTARIES. WORKSHOPS. GUESTS.

Boston Sci-Fi is a 5 day film festival. In 2026, we will be at the Somerville Theatre and locations around Davis Square. Our festival will include feature films, short films, panels, our opening night gala, and our signature event THE MARATHON. Most of these will be live with some being shown virtually.

SF51 will take place in-person February 11-16, 2026.

The SF51 means Science Fiction 51st for our 51st Marathon. A bit like Area51… Join us!

For the 2026 Festival (excluding The Marathon), about 300 films were submitted . Selections from these and curated titles add up to 10 feature screenings and 7 groups of shorts. The Marathon varies between 12 and 14 feature films. There are also workshops, special conversations, and parties.

The Marathon runs for 24 straight hours on the last day of our festival. The marathon starts Sunday at noon and finishes Monday at noon. Get your tickets today!

If attending, you watch the films as they are scheduled. A schedule will be released closer to the festival.

If you like science fiction films, yes. If you like seeing new filmmakers and the stars of the future, yes. When it comes to the Marathon, if you like staying up all night, yes. If you like making new friends and seeing different perspectives on the world, yes. Either way, you’ll have a great time.
