Launched in May 2022 at the former Bristol IMAX screen housed in Bristol Aquarium, Forbidden Worlds Film Festival is the city’s first genre film festival dedicated to screening repertory fantasy, action, science-fiction and horror films from around the world, and celebrating the people that made them.

Forbidden Worlds was created by a group of Bristol-based cinephiles in order to create a film festival dedicated to their mutual love of classic and obscure genre films that they grew up watching on VHS and a desire to see them on the big screen.

The festival has been running for two years and has drawn a lot of attention for resurrecting the city's former IMAX screen and screening genre classics on the biggest screen in the south west as well as receiving special intro videos from the likes of James Cameron, John Carpenter, Renny Harlin, Guillermo Del Toro, Jamie Lee Curtis, Peter Jackson and more.

All feature films selected for the festival line-up were, up to this point, made pre-2000 and were often available to rent on VHS or were a staple of childhood movie marathons.

As part of the festival, Forbidden Worlds now spotlights the Genre Film-Makers of the Future with a showcase of short genre films (sci-fi, action, horror) from around the world during the weekend.

The award winners are selected by a panel of judges made up of film professionals, however the Film of the Year is selected by the in-attendance festival audience who watch the shorts on a massive 18m x 15m IMAX screen and vote in-person via secure ballots. The winners will be announced on the same day.

The next festival will take place in Bristol in April 2026, and we would like to invite any genre film makers from around the world to submit their action, horror, fantasy or sci-fi shorts that they think would meet our requirements.

Tickets for the festival will be put on sale in early 2027.

If your film is shortlisted, it will be screened at the Forbidden Worlds Film Festival on the former Bristol IMAX screen in front of a live audience.

To submit a film, you must have the rights or have permission from the owner to submit the film on their behalf.

All films must have an English subtitle track included, otherwise they will not be selected for screening.

Forbidden Worlds will not pay any fee to screen short films and due to limited budget, we cannot pay for travel or accommodation for any film-makers who wish to attend the festival.

RULES AND TERMS

Please read all rules and requirements before submitting your project:

1. The film must have been made within the past two years. We do not accept any films completed before May 2025.

2. Your short can be live action or animated, documentary or fiction, however it must belong to either the action, horror, science-fiction or fantasy genre. Festival organisers might determine which genre the film best belongs to if it spans multiple genres or isn't overly clear. It must be a complete film and not a trailer, promo or sizzle reel.

3. All films must include English subtitles, especially if the film is not shot in English. This is to make the screenings more inclusive for those with hearing needs.

4. To be eligible for awards, short films must not be available for public viewing on any video hosting sites such as Facebook, Youtube, Vimeo, etc.

5. Short films should ideally be around 10 mins long, but anything up to 15 minutes may be considered subject to our panel. Please note that 15 min long films will be the exception rather than the rule!

    Excellent fest - great comms and promotion. Really take care of filmmakers. Encourage audiences to leave reviews on letterboxd. Big crowds in attendance at short film screenings. One of the best UK genre fests!

    Excellent festival. Really fun programming with lots of wacky off-beat genre films you would never normally get a change to see on the big screen. The talks were interesting and complimented the films well and there was a real positive buzz throughout.

    Great festival showing classic fantasy, scifi and horror films on the mega screen. The organisers were very friendly and helpful with the submission process. It was a privelige to debut our short film at a fantastic venue along with a well selected line up of other films and talks. Would definitely reccommend and will go again.
