Livet är en schlager (Life is a Schlager, also known as Once in a Lifetime or Hånden på hjertet in Danish) is a Swedish film released in 2000, written by Jonas Gardell and directed by his usual directing partner Susanne Bier.

[1] The film is based around the life of Mona Berglund, a mother-of-four obsessed with the Eurovision Song Contest - so much so, that her house is decorated with posters of her idols, and she has named her children after Swedish Eurovision performers: Kikki, Anna Book, Lena PH and Carola.

Mona's new-found fame takes her to unexpected places, including a TV interview, and an invitation to lunch at Berns.

Throughout, the film, though, Mona is torn as to whether she should reveal that she was not in fact the only writer of her song, and thus risk losing the public's support.

"Handen på hjärtat" was released on the soundtrack but was performed by Björn Kjellman feat.
