Omar worked with the writing and directing team of Éric and Olivier again for 2013's Samba, in which Omar plays a migrant from Senegal to France. For Omar, the story was personal, since his parents are immigrants from Senegal. "I watched a lot of documentaries and read a lot of material on immigration laws," Omar told the Travelling Boy blog in when asked how he prepared from the role. "I also had stories from my parents, but it was in the '60s and it was a different time for France and a different time for immigrants."
According to Omar, he has nothing but happy memories from his childhood in France, where he lived in a low-income suburban housing project with his parents and seven siblings. By taking on the role in Samba, Omar hoped to break down some of the stigma attached to being an immigrant. "That's why we do movies like this, just to break down the stigma that divides people," he added. "The best way to fight it is with a movie, which shows people helping each other."
