I find it odd that Mon-El/Chris Wood isn't being mentioned or seen in the promotion of the crossover. (Hank/J'onn/Harewood isn't being mentioned either, but his role doesn't seem to be as big as Wood's.) He's in some promo photos, but that's about it. He's supposed to be in the dream world too, but we haven't seen or heard anyone talk about that. It could just be them wanting to keep some surprises, but I thought at least a photo of him in the musical part would be out.
