In addition to the Austin Powers movies, the screenwriter also has credits on Mr. Peabody & Sherman, as well as the upcoming films The Boss Baby and Hotel Transylvania 3.
Both the Shrek franchise and the Austin Powers franchise established themselves for their perfect balance of witty dialogue and infantile humor.
Bringing in a writer from the Austin Powers franchise also seems like a strong indication that the next Shrek movie will appeal equally to children and adults.
Don’t worry, parents; the family friendly Shrek franchise remains in good hands with this guy.
