Many movies feature characters who have writer’s block. Not surprising, because screenwriters often bring their own experiences into their manuscripts. Adaptation is one that does a beautiful job of capturing the angst and caustic inner dialogue of the struggling writer with accuracy and humor.
One scene of Cage staring at his typewriter uses voice-over to chronicle his thoughts as he tries to decide whether he should write or eat a muffin. Guess what wins. The self-loathing and despair that Cage exudes is funny to watch but also disturbing becauseit rings true for so many blocked writers.
Of course the plot eventually presses him into situations that demand that he address his problems, but along the way we learn quite a bit about just how difficult being a writer can be, and how our own mind can torture us as we push to bring new writing out, into the light of day.
