Paddington in Perudirector Dougal Wilson explains how they managed the fantastic post-credits scene cameo at the end of the movie. While it subs out Oscar nominee Sally Hawkins for Emily Mortimer as Mary Brown, Paddington in Peru‘s cast sees a lot of familiar faces (and voices) from the previous movies, including Ben Whishaw, Hugh Bonneville, Imelda Staunton, Samuel Joslin, Madeleine Harris, and Jim Broadbent. As the Brown family embarks on a raucous adventure to Peru, they also encounter new characters played by the likes of Olivia Colman and Antonio Banderas.
