The world of the beloved Paddington bear will soon expand with a new, 26-episode CG-animated series on Nickelodeon.

The Adventures of Paddington follows a younger Paddington as he writes letters to Aunt Lucy about the new things he has discovered through the day’s exciting activities. The series premiere will air on Monday, Jan. 20 at 12:30 p.m. (ET/PT) on Nickelodeon in the U.S. Following the U.S. debut, the series will roll out globally across Nickelodeon’s international channels and branded programming blocks beginning in March.

Ahead of the premiere, Nickelodeon will introduce young audiences to The Adventures of Paddington with an early holiday presentation of “Paddington Finds a Pigeon/Paddington and the Chores List,” airing on Friday, Dec. 20, at 12:30 p.m. (ET/PT).

Actor Ben Whishaw reprises his role as the voice of Paddington, which he performed in the recent theatrical films. Gary Barlow of UK hitmakers Take That penned an original theme song, “Paddington Bear,” which he also performs.

The Adventures of Paddington will be supported by content on nickjr.com and the Nick Jr. app, with episodes also made available on Nick Jr. on-demand and download-to-own services in the U.S.

The series is directed by Adam Shaw and Chris Drew of BlueZoo (Go Jetters, Digby Dragon, Miffy), and developed for television and written by Jon Foster and James Lamont (The Amazing World of Gumball, Paddington 1 & 2). The series is executive produced by David Heyman (producer of the Harry Potter films, Paddington 1 & 2) and Rosie Alison (Boy in the Striped Pyjamas, Paddington 1 & 2), with Karen Davidsen (formerly with Disney and HIT Entertainment) and Simon Quinn (Isle of Dogs, Fantastic Mr. Fox) serving as producers. Rob Silva is co-producer.
