So in watching it he enjoys basking in the celebrity life? And the scheming?
Trumpty spends his whole life scheming to gain advantage. But I think he enjoys the movie because it's a classic; he doesn't see himself as Norma. Probably he thinks he's as good looking as William Holden and as important as Cecil B DeMille.
Watch the clip, and see if you can find the whole movie somewhere. It's very good. A classic.
