It’s Sidney Poitier night on TCM, an evening that begins at 8 p.m. ET with The Defiant Ones. But for me, the centerpiece is his inspirational 1967 film To Sir, with Love, in which he plays a young black teacher assigned to teach at a tough Eastenders school in England. Teenage singing star Lulu sings the title song and plays one of his students, Judy Geeson and Suzy Kendall also co-star, and I’m pretty sure this is what inspired me to want to become a teacher.
