The two teenagers on the screen trudging through the endless dunes of the Sahara on their way to Europe were actors. So were the fellow migrants tortured in a bloodstained Libyan prison.

But to the young man watching the movie one recent evening in a suburb of Dakar, Senegal’s capital, the cinematic ordeal felt all too real. His two brothers had undertaken the same journey years ago.

“This is why they refused to send me money to take that route,” said Ahmadou Diallo, 18, a street cleaner. “Because they had seen firsthand how dangerous it is.”

Critics in the West have praised the film “Io Capitano” — nominated for the 2024 Academy Award for best international feature film — noting its visceral yet tender look at migration to Europe from Africa. It is now showing in African countries, and is hitting close to home in Senegal. That’s where the two main characters in the movie embark on an odyssey that epitomizes the dreams and hardships of countless more hoping to make it abroad.

Last month, the film’s crew and its director, Matteo Garrone, took “Io Capitano” to a dozen places in Senegal where migration isn’t fiction. They screened it in youth centers, in schools, even on a basketball court turned outdoor movie theater in Guédiawaye, a suburb of Dakar, where Mr. Diallo and hundreds of others watched it at sunset on a big screen.
