The Observer has posted some news from their sources on Keanu’s character in Toy Story 4. They posted the following:
Keanu Reeves is playing a character named Duke Kaboom, who hails from a place where discontinued toys are sent (we’re totally getting an original GameBoy cameo, aren’t we?). Apparently, Bo Peep (voiced by Annie Potts) seeks out his help in retrieving her sheep after they’ve been taken from her. So, essentially, Reeve’s Duke Kaboom is the John Wick of toys.
