Before becoming the president of Ukraine in 2019, it’s now well-known that Volodymyr Zelensky made a living as an actor and comedian. However, new details reveal that he also voiced the Peruvian bear named Paddington in the Ukrainian-dubbed versions of the children’s films.
StudioCanal has confirmed to THR that Zelensky not only voiced the marmalade-loving bear in the 2014 original film, but he also voiced the character in the critically acclaimed sequel Paddington 2.
In an unearthed promotional video for Paddington 2, Zelensky is taped recording his lines over some silly clips of Paddington, and he shares a message for the film.
