“It’s basically what happened,” he said. “It’s the truth. Certain things that happened, like when my father died, were a little different, but 95 percent is the truth.”

His father, Don, died Dec. 2, 2007, after attending a Knicks-Suns game.

The supporting cast is familiar to basketball fans as well. Allen Iverson has a cameo as himself. Another former player, Baron Davis, appears as, according to Marbury, "a guy who is like the foreigner of the other team who we played against to beat in the championship.”

While Marbury modestly awards his own acting skills a “four or five,” he said: “Baron was like an eight or nine. He’s really good.”

Looking to appeal to every demographic, the film also features Jessica Jung, a former member of the K-pop group Girls’ Generation, as Marbury’s manager.

“The people loved the movie,” Marbury said after the festival. “This will give people an understanding about what happened. It’s inspirational. When you hear about a black guy with a statue in Beijing, they wonder how a foreigner comes to a country and receives all these high honors."

There is indeed a statue of Marbury in Beijing. “People say it doesn’t look like me,” Marbury said. “But I know it does, because I know the face I made when they made the statue.”
