The affable actor proceeded to lead the crowd in an impromptu singalong of the show’s iconic theme song, “Won’t You Be My Neighbor”.

ET Canada caught up with Hanks on the TIFF 2019 red carpet, where he discussed what he learned from portraying Fred Rogers, praising the late educator’s authenticity. “You have to look at his output on television, and it was singularly honest,” Hanks explained.

“And I think you’d easily dismiss it because it was an honestly that wouldn’t have mattered to you and me… he just wanted to make little kids, little human beings, feel safe even if they didn’t have all the answers.”
