This is an American movie. I don't think it's very old, maybe 90's at the latest but most likely 2000's. There is an African American who is either an intern or a student, I want to say it's at a college. He is mentored by a European American professor or doctor, and encouraged to become a doctor himself. I think it's based on a true story, and I want to say the African American doctor becomes the first African American to perform open heart surgery or something. I remember the African American is played by a rapper, and I want to say the European American is a famous actor but I can't remember who he is or what else he was in.
Does this movie sound familiar to anyone? I saw it on HBO a few years back so it may have been an HBO production and not released in theaters.
