How Tim Key got Carey Mulligan in The Ballad of Wallis Island

The film “The Ballad of Wallis Island” tells the story of Charles, an eccentric lottery winner who uses his money to hold a private concert on the remote Welsh island where he lives. The band he hires is his favourite group of all time: the fictional folk rock duo McGwyer Mortimer. The only problem is they haven’t spoken in years — and the concert is just for Charles. British poet and comedian Tim Key stars as Charles and co-wrote the movie, which is based on a short film he made in 2007. Earlier this year, he joined Tom Power to talk about the project and why it took 18 years to turn his short into a feature. Plus, he reveals how he persuaded Hollywood A-lister Carey Mulligan to get on board.
