Taylor Swift chased her dream of being a music superstar for quite some time, finally landing on top. And she saw a similar struggle in Paul Potts of 'Britain's Got Talent.' The superstar talks 'Sweeter Than Fiction' and her inspiration for the song in a new 'One Chance' trailer.

The songstress co-wrote the song with Jack Antonoff from fun., and the trailer gives fans a look at the two singers collaborating in the studio, as well as clips from the movie, 'One Chance.' There is also an interview with Swift herself, which is interspersed into the footage, and fans can get a firsthand look at the film that inspired the catchy and meaningful track.

"Getting to see the struggles and triumphs of someone who never stopped chasing what he was after really inspired me," the songstress relates.

After seeing the clips from the movie -- ranging from Potts' character sitting devastated on his bed, running from bullies, to falling in love and standing onstage at the singing competition -- we can't help but think Swift's song is perfect for the closing credits.

The lyrics sum up the 'One Chance' plot incredibly well, and you can't help but feel that Potts' story is truly sweeter than fiction. Swift also believes the Britain star's story is incredible. "It's a beautiful movie, and I just wanted to share it with as many people as I could," she shares.

The film, which hits theaters in the U.K. theaters Friday (Oct. 25), will be released in the U.S. on Dec. 27, 2013.
