There is a scene in “Green Book” where we first see Oscar-winner Mahershala Ali (“Moonlight,” “Hidden Figures”) play piano and it’s a beautiful thing to watch because you believe every note and nuance of the music is coming from him personally. That is acting, and that’s what happens when good films are made on a higher level. Mahershala also practiced for months.
