Will Smith learned a lot from Uncle Phil, on and off screen.
The actor is speaking out about his "Fresh Prince of Bel-Air" costar James Avery's death, memorializing him in a new Facebook post and sharing the last photo of the cast together.
"Some of my greatest lessons in Acting, Living and being a respectable human being came through James Avery," he writes.
"Every young man needs an Uncle Phil. Rest in Peace," Smith adds in his statement.
Will also posted a shot of him, James, Alfonso Ribeiro, Karyn Parsons and Tatyana Ali, which was taken when they reunited at a charity event back in 2011.
"This photo was the last time we were together," Smith wrote in the caption.
See how the rest of the cast remembered James on Twitter below -- and see how the rest of the stars of the classic sitcom have aged in the gallery above.

Sending condolences to the family of James Avery, "Uncle Phil" of the Fresh Prince. I'll always remember how warm he was to me on set.
