'Toy Story 4': Keegan-Michael Key Discusses How Beloved Characters Have Changed (Exclusive)

The veteran comedian also discusses participating in 'The Lion King' remake!

Keegan-Michael Key is spilling some new details on Toy Story 4!

The 48-year-old actor, who's reteaming with his Key & Peele co-star, Jordan Peele, to play carnival prizes Ducky and Bunny in the movie, chatted with ET at the upfronts in NYC on Tuesday for National Geographic's Brain Games reboot about the upcoming animated film.

"I have seen the finished product," he teased, before adding, "I laughed, I cried, I was inspired...I've seen them all. I know I'm partial. It's my favorite."

He also praised his fellow newcomers to the franchise. "I gotta tell you, Tony Hale is unbelievable in this thing," Key said of Hale's Forky, a frantic spork made of pipe-cleaner, googly eyes and a rubber band. "Christina Hendricks, other people I can't tell you about, 'cause I don't wanna ruin the surprise, but it's so good."

Key went on to hint that, although the sequel is loaded with classic Toy Story characters like Woody (Tom Hanks) and Buzz Lightyear (Tim Allen), some have been updated a bit.

"It's so action-packed," he added. "And there are old characters coming back that you, that we learn new things about whose lives have changed. It's gonna be amazing."

We've already gotten a taste of what Key is discussing in recent trailers: Bo Peep (voiced by Annie Potts) will be returning for the fourth installment with a fresh new look and attitude.

During the interview, Key also gushed about what fans can expect from the upcoming live-action remake of The Lion King, in which he plays Kamari, one of the hyenas who serve Scar. "The photo-realistic treatment they've given to it is amazing," he said. "It's more dangerous, more grave, more funny, more Beyoncé! This thing is gonna make a quadrillion dollars!"

Toy Story 4 arrives in theaters on June 21 and The Lion King opens on July 19. Meanwhile, the Brain Games reboot will premiere on Nat Geo in December 2019.
