This is a hard film to categorise and review. It's by the people who brought you Being John Malkovitch, which should warn you that it's a bit weird. It's about the writer of that film Charlie Kaufman and his fictional brother Donald (who gets a writing credit and was jointly nominated for awards). Charlie is trying to write a script for a real book called The Orchid Thief, but is having some problems. Meanwhile his brother decides to be a script writer too in a more mainstream way.
Nicholas Cage plays both of the brothers and Meryl Streep is the book author. It's basically a film about writing that film and so is a bit up it's own behind. However, I enjoyed it as a comedy. It made me laugh a few times and kept my brain working. It's tempting to investigate the characters further to see how close to the truth it is or if it's all made up.
I'll give it 3/5
