Balladic videos by the medium’s vertiginously hip Peter Pan cast him or his collaborator, Benjamin Brock, as Michael Jackson being pathetically boyish in the snow; and old-school British dandy channelling Gene Kelly in “Singin’ in the Rain” (soaked by a digitally animated little cloud) on Rossevelt Island; a “2001” astronaut prowling the deserted Museum of Natural History; and one among many “Star Wars” Stormtroopers marching and milling at a desultory fan convention. Stylistic virtuosity (wittily referential cinematography, sonorously layered sound) and tasty allusion (Oscar Wilde here, F. W Murnau there) subilize without imperilling a determination not even to think about growing up.
