Disney Branded Television has unveiled the trailer for “The Sign,” the first extended-length special of the hit series Bluey, premiering 14 April at 3 p.m. on Disney+.

Bluey is starting 2024 as the No. 1 most streamed series across all audiences and the No. 1 series for preschoolers and kids overall in the US, according to Nielsen.

“The Sign” is the longest episode ever of the global hit TV show. Dave McCormack and Melanie Zanetti reprise their roles as the voices of Bandit and Chilli Heeler, and Patrick Brammall returns as the voice of Uncle Rad; Claudia O’Doherty as Frisky, alongside Megan Washington as Calypso; Myf Warhurst as Trixie; and Rose Byrne as Aunt Brandy. Making their Bluey voice debut, this special episode introduces Rove McManus, Deborah Mailman, Brendan Williams and Joel Edgerton.

Created and written by Joe Brumm, the series follows Bluey, a lovable and inexhaustible Blue Heeler dog who lives with her mum, dad and little sister, Bingo. Bluey uses her limitless energy to play games that unfold in unpredictable and hilarious ways, bringing her family and the whole neighborhood into her world of fun.

Jointly commissioned by ABC Children’s and BBC Studios Kids & Family, Bluey is produced by the multi-Emmy Award-winning Ludo Studio for the Australian Broadcasting Corporation and BBC Studios Kids & Family. The series airs and streams to US and global audiences (outside of Australia, New Zealand and China) on Disney+ through a global broadcasting deal between BBC Studios Kids & Family and Disney Branded Television.
