Feel free to ignore any news on Ghostbusters 3 until it gets in front of cameras, but if you are still curious, Aykroyd spoke about Ghostbusters 3 on Larry King Now [via Coming Soon]:

“It’s based on new research that’s being done in particle physics by the young men and women at Columbia University. … There’s research being done that I can say that the world or the dimension that we live in, our four planes of existence—length, height, width and time—become threatened by some of the research that’s being done. Ghostbusters, new Ghostbusters, have to come and solve the problem.”

Bloody Disgusting shared these details for the Poltergeist remake:

The new version follows Eric Bowen and his family who, after he loses his job, relocate to a new town to start anew. His daughter, Madison, is abducted, making him truly understand what’s important in life: family. In the new version, Eric’s wife, Amy, can communicate with the dead. Another interesting new character is Carrigan Burke, a television personality who hosts “Haunted House Cleaners.” The supernatural doesn’t scare this guy. Dr. Brooke Powell is Carrigan’s ex-wife who is a parapsychologist at a local university. Her team investigates the supernatural events surrounding the disappearance of the Bowen girl.

When asked about the latest Jurassic Park project, Neill said to the Dominion Post, “I’m told it’s a big reboot, a total re-jig.” This may just be a miscommunication, since producer Frank Marshall told us the project is not a reboot. But Universal recently put Jurassic Park 4 on indefinite hold, so there is some possibility that if/when Jurassic Park returns, it may be in the form of a reboot.
