A Piece of My Heart (Swedish: En del av mitt hjärta) is a Swedish jukebox musical film directed by Edward af Sillén and written by Lars "Vasa" Johansson [sv] based on music by Tomas Ledin.

[4] Af Sillén described the film as an "all in-musical comedy" with a great ensemble and big, lavish shownumbers.

[5] The plot follows Isabella, a successful business woman in the financial district of Stockholm, who returns to her small-town home to celebrate her father's birthday, only to find her teenage crush is marrying her childhood best friend.

[8] In November 2019, private previews of the English version were screened for invited guests in the hope of establishing a further international release.

Ledin asked Ulvaeus if he would be interested in writing English lyrics for his songs as they are long time friends.
