One weekend.
One prompt.
One short film.
A cinematic sprint with real stakes.
The 24 Hour Film Challenge exists to compress the creative process into one unforgettable weekend — testing everything from writing under pressure to on-the-day producing to overnight edits. Every finished film screens on the big screen, in front of a jury of working industry professionals.
It's the fastest way to make a film that opens doors. Past winners have gone on to sign with agents, land staff writing rooms and secure short-form commissions from CCW partners.
Three steps to the start line.
Register your team
Sign up as a team of 4–10 or as a solo creative — we'll match solos into teams beforehand.
Show up on Friday
Turn up at the CCW studio at 18:00 for the opening ceremony and prompt reveal.
Deliver by Sunday 17:00
Upload your finished film before the deadline — screening and awards follow at 18:00.
48 hours, minute by minute.
Opening ceremony & prompt reveal.
Teams gather at the CCW studio to collect their prompt, genre and required element for the weekend.
Writing sprint begins.
Teams have four hours to lock a script — CCW mentors are on hand for late-night notes.
Production day.
Shoot day across Wales — teams have full autonomy over location, cast and craft choices.
Post-production takeover.
Edit suites open across Cardiff for teams needing space, gear or a colourist to lean on.
Screening & awards night.
Every film screens on the big screen at Chapter Arts Centre. Judges announce prizes on the night.
The essentials.
