I thought that there might be something unsatisfying about directing two Tolkien movies after 'Lord of the Rings.' I'd be trying to compete with myself and deliberately doing things differently.
The Tolkien estate owns the writings of Professor Tolkien. 'The Hobbit' and 'The Lord of the Rings' were sold by Professor Tolkien in the late '60s, the film rights.
Second movies are great because you can drop into them, and it doesn't really have a beginning on it, particularly in a traditional way. You can just tear into it.
