WarnerMedia Kids & Family has greenlit Cartoon Saloon’s new preschool comedy series Silly Sundays. The 2D-animated show will premiere in the US as part of the HBO Max/Cartoon Network preschool block Cartoonito in 2023, before debuting internationally in LatAm and EMEA.

Ireland’s public broadcaster RTE has also picked the series up, but a premiere date in that region hasn’t been set yet.

Silly Sundays centers around three cousins who create unforgettable memories together during weekend gatherings with their extended family. Created by Oscar-nominated producer Nuria González Blanco (Late Afternoon), the project in production now in Kilkenny, Ireland. Blanco and Fabian Erlinghäuser (Wolfwalkers) are directing the series, which was first pitched at the 2018 edition of Cartoon Forum, where it was a standout crowd-favorite.

Silly Sundays has been developed and produced with assistance from Screen Ireland and Creative Europe. Cartoon Saloon Brand Development is handling ancillary and merchandising rights, and has partnered with Superights for distribution outside of the regions covered by the WarnerMedia commission.

Superights and Cartoon Saloon have worked together previously on distributing preschool series Puffin Rock, which has since been picked up by broadcasters in Norway, Sweden and Australia, as well as by Netflix in multiple territories.

WarnerMedia’s Cartoonito block launched on September 13 with 20 content titles and the promise of  50 more within two years. Silly Sundays is part of Cartoon Network’s push to broaden beyond boys ages six to 11 and also serve preschoolers, girls and families.
