Sidney Poitier’s barrier-breaking legacy is now back on the big screen. The Documentary “Sidney,” directed by Academy Award nominee Reginald Hudlin (“Marshall”), focuses on Poitier’s career as an actor, filmmaker, and activist during the Civil Rights Movement. Interviews with Denzel Washington, Spike Lee, Halle Berry, Robert Redford, Lenny Kravitz, and Barbra Streisand frame the film, which is produced by Oprah Winfrey and Derik Murray in close collaboration with the Poitier family. Winfrey’s Harpo Productions and the Network Entertainment produce the Apple Original Film, set to debut September 23 on AppleTV+ and in select theaters.
