Sony is attempting to create a Ghostbusters universe similar to what Marvel has been able to achieve. This will start with Paul Feig’s all-female take on the property that arrives next year and continue with a second movie that stems from the real life chemistry between friends Channing Tatum and Chris Pratt. After those films release, there is a plan for a third film where both teams will interact, similar to The Avengers.
Rumors are that the movies will have nothing to do with the original human characters due to issues with rights, but some of the more famous ghosts could appear.
