Williams played President Dwight D. Eisenhower in Lee Daniels' "The Butler" in 2013.
The last Williams film to be released while he was alive was 2014's "The Angriest Man in Brooklyn," which co-starred Mila Kunis.
"Night at the Museum: Secret of the Tomb" was the last studio film Williams had completed prior to his death. He posted this photo with his stand-in and stunt double in May 2014.
The last photo Williams ever posted to social media was this #tbt featuring him with his daughter on July 31: "Happy Birthday to Ms. Zelda Rae Williams! Quarter of a century old today but always my baby girl. Happy Birthday @zeldawilliams Love you!"
