Everyone who saw Thor: Ragnarok, Moana, or What We Do in the Shadows knows that director Taika Waititi is a funny guy. Now his sense of humor is pointed directly at rival superhero film Justice League.

Waititi recently tweeted a portion of the Justice League poster, a subliminal message that spelled out the title of his own movie: “Thor.” The fact that this shout-out comes from the director of Thor himself makes it even more amusing.
