This sounds different-- Johnny will play the lead in an animated series about puffins! It will be a series of 250 five minute episodes, which sounds like that new mobile streaming service (I forget the name) where everything is less than like 8 minutes. There was a Telegraph UK article which wouldn't let me read the whole article, but it said his character will speak in a made-up language, which certainly sounds right up Johnny's alley
This is in collaboration with the producers of Waiting For the Barbarians. Maybe I'll have to get this streaming service??
