Potter director 'agonised' over film split

Director David Yates "agonised" over the decision to split 'Harry Potter and the Deathly Hallows' into two films.

The filmmaker always knew he would never be able to fit the final instalment of the boy wizard franchise - based on the best-selling books by J.K. Rowling - into one movie, but couldn't think at first of a way to split it in two.
