Does anyone else see this as part of a trilogy with ...?
Adaptation and Synecdoche, New York.
Not just because they were all penned by Kaufman but their themes match perfectly think about it:
Being John Malkovich - Acting
Adaptation - Writing
Synecdoche, New York - Directing
Eternal Sunshine of the Spotless Mind (my favourite Kaufman film btw) I don't count because the theme of it - memories- doesn't really fit.
