While I'm here I think I'll add that as always I have a thing for Anne Hathaway and I wish they would have called me to play Dexter in this. In my opinion it would have made for a much more interesting movie, although it may have lost that PG13 rating. "One Day" is adapted for the screen by David Nicholls from his bestselling novel of the same name.
