Some film franchises take forever to get the sequels fans have been waiting for. The most obvious example is probably Star Wars, which went through 16 years of downtime between Return of the Jedi and The Phantom Menace. However, the second trilogy was a set of prequels, so in actual fact, the news that Star Wars will get a direct sequel in 2015 places the sabbatical at 32 years.
Another movie franchise that's gone quite a while without having a follow-up is Ghostbusters. The first installment was released in 1984, and Ghostbusters 2 hit theaters five years later. However, since 1989, the director, actors and producers haven't been able to successfully bring the series back.
Earlier this year, star and writer Dan Aykroyd announced that filming was going to go forward. The holdup came from Bill Murray, who apparently didn't want anything to do with any more Ghostbusters movies. However, the original cast decided to move forward without him, and shooting was intended to begin next summer.
However, ComingSoon.net is reporting that there has been yet another delay. There have apparently been some problems with the script, which is being written by Etan Cohen, so filming can't begin until the fall of 2013 at the earliest. That places a release date somewhere in the vicinity of 2014.
