Andrew Stanton admits 'Toy Story 4' is a "possibility".
The 'John Carter' director has previously written all of the 'Toy Story' animated movies – about the secret lives of a group of play things owned by a young boy – and although he admits he has to "come up" with something good, he is not scared by the prospect.
Speaking at the UK premiere of 'John Carter', Andrew said: "There's always the possibility for a new movie, it just comes down to only if there's a story good enough.
"We've set the bar so high with the previous three movies that as much as people want a fourth nobody wants an inferior movie so we've got to come up with something good."
With his new movie, Andrew admits he was delighted to get Taylor Kitsch on board because people find him hard to "stop watching".
He added: "Taylor just has that X Factor. Do you really need to ask me? Can you not see the Taylor effect? You can't describe it, there's something about him that you just can't stop watching and you mix that with his charisma and that he's a really great actor."
