_Gods and Monsters_ shows James Whale copying famous works of art.
Not a film, but the game _Super Mario 64_ has Mario jumping in and out of paintings like a more explicit (entrance and exit wise)
version of Kurosawa's "Crows" FWIW.
"It's a queer world, and the longer I live in it the queerer I find it. Once I thought it would be a good idea to regulate things myself, and run the world as it ought to be run; but I gave it up long ago. The world's a stage, they say; but the show ain't always amusing, by a long chalk, and sometimes I wish I didn't have a reserved seat."--John Merrick, _Aunt Jane's Nieces_, by L. Frank Baum
