Sonnefeld explained, "Will calls me Baz. When we were shooting Men In Black 2, one night he said 'Hey Baz, I think I have an idea for number three'. The basic idea was that Will's character, Agent J, would have to go back into the past to save his partner. It allowed the movie to take place in another era, and us to learn more about Tommy Lee Jones' character.”
He added, “But it turned out to be a very long process of development, mainly because of the knotting issues of time travel, the time travel thing was really hard." Barry then revealed how they began shooting Men In Black 3 before the official script for the movie had even been completed, making things very difficult.
Sonnefeld continued, "We knew starting the movie that we didn't have a finished second or third act. Was it responsible? The answer is, if the movie does as well as I think it will, it was genius. If it's a total failure, then it was a really stupid idea." You can catch Will Smith, Tommy Lee Jones and Josh Brolin in Men In Black 3, which is released on March 25.
