The film follows Bea (Sydney Sweeney) and Ben (Glen Powell), college archnemeses who are forced to reunite years after graduation for a destination wedding. Instead of tackling their issues head-on, though, they decide to pretend to be in love.

In the film, Unwritten isn’t simply a song in the background; it stands firm as its own character in Bea and Ben’s love story. The song features as Ben’s ‘serenity’ song and crops up multiple times during the film. This has kicked off a trend on social media, and especially on TikTok.

“I knew the song would be part of the film, but I had no idea that it would be in there so much. It really did blow me away!” Bedingfield says. “I love seeing people skipping out of watching a romcom and singing my song because that’s definitely the feeling that we had when we first wrote and released it.”

This isn’t the first time that Bedingfield’s songs have popped up in romcoms. You might remember the famous scene in Easy A where Emma Stone’s character receives a musical card with Pocketful Of Sunshine playing, which then inspires her to sing the tune constantly, even in the shower.

“I think pop songs have an element of comedy in them,” Bedingfield shares. “I co-write my music with other people and it feels like we’re in a Saturday Night Live room – sitting around, making jokes all day. I hope that comes through in the songs and maybe adds something joyous and positive to the romcom genre.

“My friends have written dirty versions of Unwritten. There’s an element of songwriting where there’s no wrong lyric or wrong answer. Everything and anything goes and, in that kind of environment, you end up with some gems along the way.”

Bedingfield isn’t the only artist who’s seeing new success from their old music due to the Hollywood effect. In Emerald Fennell’s Saltburn, the iconic final scene sees Barry Keoghan’s character dancing naked to Sophie Ellis-Bextor’s 2001 single Murder On The Dancefloor. The song was propelled to the No 2 spot in the UK charts – more than 20 years after the song was initially released.

“The great thing about platforms like TikTok is that artists get to see and engage with what these songs mean to people – including new audiences who are just discovering them – and the feeling they get from songs like Unwritten and Murder On The Dancefloor,” Bedingfield says. “It’s one of the favourite parts of my job, I love seeing people share their joy in my songs.”
