He'll be great! He can easily sing Hello, Little Girl.
But I like that he's "nervous" about it. That will keep him on his toes, fresh, and spontaneous. A lot of inventiveness can come out of nerves. But I have no doubt his Wolf will be one of the highlights of the film.
I do think this scene, in a major motion picture by Disney, is going to be a tad tricky. A lot of it will depend on who is cast as Little Red, her age, her development (emotionally and physically) and how the two actors play off of each other.
But obviously, this can run the gamut from playful and goofy to full-on sexual predator. I really don't think they have to go too far into the latter. The audience's (dirty little) minds will gladly complete the circle.
Still, I imagine they will film this scene and song a few times, several different ways, and find out just how far they could and should go with it before it becomes ... icky.
