I think a teaser it's coming either today or on April with Bad Guys. Illumination likes to show the market their films with A LOT of anticipation.
-The first teasers of Despicable Me 2 and SLoP were released more than a year earlier before the movies hit theatres.
-The teaser of the first Sing was released on February 15th (11 months before Sing hit theatres, and Mario it's coming on 11 months from now)
-Grinch and first Minions had their trailers 10 months before the movie release
Semi unrelated question - Once The Batman presales starts, which would be the best comps for tracking?
I would suggest No Way Home, Venom LTBC, BvS and Captain Marvel
Universal had a 17 days window for the films that opened with less than 50M (Old was their only sub 50M to have a longer window, because Shyalaman financed it, I guess). Last year Croods 2 had the same window and still legged well.
They are starting to cast singers that are popular among teens/young adults. Harry Styles will be in Don't Worry Darling, Ariana Grande is on Don't Look Up and will be in Wicked, Dua Lipa will be in Argylle, and Taylor Swift in David O Rusell's next movie
