Peter Jackson has admitted "I didn't know what the hell I was doing" during shooting of the "Hobbit" trilogy.
The Oscar-winning director makes his candid admission in a behind-the-scenes video (embedded above) for the DVD and Blu-ray release of "The Battle of the Five Armies", the final film in the "Hobbit" trilogy.

Those films returned to J.R.R. Tolkien's Middle-earth after Jackson's hugely successful "Lord of the Rings" trilogy, a global phenomenon that did staggering business and earned Oscars for Best Picture and Best Director. The weight of expectation on "The Hobbit" movies was therefore huge -- but Jackson and his crew also had a huge problem.

In stark contrast to the extensive planning of the "Lord of the Rings" movies, which saw three and a half years of pre-production, there wasn't enough time to fully plan out the "Hobbit" films. That's because Jackson only stepped into the director's chair after Guillermo del Toro dropped out, meaning that the film had to be redesigned from scratch.

According to the crew, that made shooting "a bit chaotic", to say the least. "No department ever got ahead," says one crew member, while another remembers how, "Almost every morning of the shoot, we were delivering the objects needed that day."
