The movie whose name I couldn't recall in 170-01 today is Last Action Hero. It's longer than it should be but still a lot of fun, I think. By far the best minute-and-a-half or so is this clip, in which the protagonist, a young boy named Danny whose hero is the action-movie star Jack Slater (Arnold Schwarzenegger), is watching the Laurence Olivier film version of Hamlet. Impatient with Hamlet's indecisiveness, he fantasizes how a particular moment in the play might have unfolded with Slater in the lead role.
We're seeing here the power of the imagination to overcome the restrictions of a reality that is itself a product of imagination. I suspect Carroll would like that.
A particularly nice touch: Danny's fantasy is realized not in an ad hoc way but through the conventions of a particular cinematic genre: the trailer.
