Roro's Swedish girlfriend Lisa (Tuva Novotny) wants to be introduced to his family but he refuses for a long time because of his Lebanese family traditions.
After returning to Sweden in 2000, Lemma recorded the soundtrack to Josef Fares' movie Jalla! Jalla! (which in turn rendered Lemma a Grammis nomination for best song, the romantic "If I Used to Love You").
He is the brother of director Josef Fares, and has several times played major parts in his films, including Jalla! Jalla! (2000) and Kopps (2003) and son of father Jan Fares, also an actor.
