There were several tweets by members of the production crew for Jurassic Park IV who have said that there are major disagreements in the script and that the production of the fourth film may go on hold indefinitely. However, Universal has answered, “disagreements between those working on the project and the Studio, which has resulted in an overhaul within the film’s production crew.” This means that the film might not be able to make it’s June 2014 release date. The next couple of days will determine if the release date changes, stays the same, or disappears.
