The letter sent to Thomas by the Penguin Group at the end of the film has a typo in it: where it reads 'I with you every success with your book...' should actually be 'I wish you every success with your book'? Didn't expect that from the 'Penguin Group'.
The Penguin Group sends a letter to Thomas near the end of the movie. It contains not one, but two typos: One is mentioned in another post ('with' instead of 'wish'), the other is the second last word of the main paragraph ('youtr' instead of 'your').
