Okay first off: do not use this as a way to spread rumors about a PJ Masks film being confirmed, that's just stupid.
But i mean: It's possible isn't it? Shows for little kids have gotten movies centered around them before. Barney has one, Dora has a couple (although i think all of them were made for TV). PAW Patrol is getting one come next year, My Little Pony has one and is getting another..this show is extremely popular right now. Not making a movie about it while the oven is hot would be a big missed opportunity for EntertainmentOne!
