Peter Jackson attended Comic-Con this weekend to screen clips and to speak about his upcoming two-part film adaptation of J.R.R. Tolkien's The Hobbit, and teased that he may have a third film planned.

The New Zealand-born director spoke to HitFix at the convention and said that the team behind the film project are looking into splitting the second part of the film into two separate films "We have certainly been talking to the studio about some of the material we can't film, and we've been asking them so we can do a bit more filming next year".

"I'd like to shoot a bunch more material that we [couldn't] shoot. There's so much good stuff in the appendices that we haven't been able to squeeze into these movies" he added.

The Hobbit follows the story of Bilbo Baggins and a group of dwarves embarking on an adventure, Irish actor Aidan Turner plays one of the dwarves, Kili.

Jackson further explained that the author first published The Hobbit in 1936, followed by the Lord of the Rings books almost twenty years later, and so he had revisions and notes linking the two stories which the director would like to see come to life on the silver screen.

The 50 year-old director shot the two films back to back in New Zealand to depict the tale of The Hobbit. The first installment, The Hobbit: An Unexpected Journey is due for release in mid-December, with the second film, The Hobbit: There and Back Again, due for release in December 2013.

The director also spoke to The Huffington Post at the convention. Jackson spoke of the pressure he received to produce a film version of the prequal book to the Lord of the Rings trilogy. "When I did the Lord of the Rings movies, all three of them, each year, everybody would be asking me, 'So are you going to move on to The Hobbit? Is The Hobbit going to be next?' And it wasn't actually possible at that time, anyway, because of the rights situation with MGM and Warner Brothers."

"But I'm glad I didn't do it then" the director proclaimed, "I didn't really want to do it then, and I've gone off and done other things. And so, the return to Middle-Earth has been much more of a pleasure...it feels less like a duty and more like a reunion".

Jackson humbly quipped that he is not a good judge of his own films, in general, "I still look at movies that I've made and I look at the scene and I'm thinking of the rain that happened that day or the camera crane that broke down and the things that happen. I kind of can't quite divorce it from the actual experience of making the film".
