About Dunk
Dunk is a made-up brand, invented by Big Screen Hack for this challenge. It is not a real company, you can't buy one, and it has nothing to do with any real hot tub or ice bath brand.
The idea: Dunk makes two things for ordinary British back gardens. The Simmer is an inflatable hot tub. The Shiver is an ice bath. Same garden, same people, very different noises.
The brief
This is the fun challenge. No client, no brand manager, nobody to keep happy. Make us laugh.
Make a Black Friday or Christmas ad for Dunk, 20 to 60 seconds long. Your ad can be for the hot tub, the ice bath, or both at once.
The one thing to get across: hot or cold, the best seat in the house is in the garden. The Simmer is for people who want to lie back and say “ahh”. The Shiver is for people who want to get in and say something we can't print.
Who it's for: couples, families and groups of friends with a small garden, patio or deck. One of them always wants the hot tub. One of them always claims to love the ice bath.
How Dunk talks: warm, dry and a bit cheeky, the way a friend would say it. Short sentences. British understatement. The line that ends every ad is “Go on. Have a dunk.”
What to show: steam and ice on a cold night, frost, fairy lights, woolly hats, mugs of tea, dressing gowns by the back door, and the face people pull in the first three seconds of an ice bath.
What you can say about the products, all made up: the Simmer goes up in about ten minutes with no tools, plugs into a normal socket and heats to 40°C. The Shiver holds one person and a lot of ice. If you want a price or an offer in your ad, make one up and keep it believable.
Don't make health claims, don't promise running costs or savings, and don't mention or copy any real hot tub or ice bath brand, its product names or its adverts.
Brand kit
Colours
Garden Green and Towel Cream do most of the work. Ember is for hot, Ice is for cold: use both sparingly.

The rules
For this challenge
- This is a fun challenge. Dunk is a made-up brand, so it has no prize of its own. Your ad is an entry for The Big Sell, and The Big Sell's rules apply.
- Make it on OpenClips.
- It must be between 20 and 60 seconds long.
- It must be a Black Friday or Christmas ad.
- It can be for the hot tub, the ice bath, or both.
- Use the Dunk logo and colours from the brand kit. The pictures in the kit are there to work from: you don't have to use them as they are.
- Don't mention, show or copy any real hot tub or ice bath brand, its product names or its adverts.
- No health claims, and no promises about running costs or savings.
- You keep your ad. Dunk isn't real, so nobody takes ownership of it.
For every track and challenge
- Entry is free.
- Enter on your own or as a team. You don't need a ready-made crew: you can find collaborators among the people taking part.
- Entries close at midday (UK time) on Sunday 11 October. Early submissions are guaranteed to be judged.
- Unless the brief says otherwise, you can make something new during hack week or enter work you've already made, as long as you hold the rights to it.
- You keep what you make. Big Screen Hack gets the limited rights in the chapter terms to judge, screen, promote and archive your entry, and everyone in your team must have the authority to grant those rights.
- Before any public screening, you tell us who owns the script, which AI models you used, any material shot with real people, permission for anyone's likeness, the music rights and any territory restrictions.
- Sponsors' challenges are judged separately from the independent main jury.
- Partner credits are one code per person for each partner, redeemed on the partner's own platform.
- The shortlist premieres on Friday 16 October at the IMAX.
The full rules for the event, including rights and what you need to tell us about how your entry was made, are in the participant guide.
Prize and judging
- There is no separate Dunk prize. A Dunk ad competes for The Big Sell: a US$1,500 cash prize and an award presented by OpenClips on premiere night.
- The winning ads play on the IMAX screen before the films on Friday 16 October.
- Judged with the rest of The Big Sell, by that track's jury.
