We haven't heard much about Jurassic Park IV, which is currently being written by Mark Protosevich. It wasn't known if Steven Spielberg would return to direct, but now the filmmaker revealed he will not be at the helm. Here's what he had to say below.

"I don't want to talk about Jurassic Park IV yet - it's too early - but I can tell you that I'm not directing it. I'm producing it though."

Another follow-up he will be producing and not directing is the Untitled Tintin Sequel, although Steven Spielberg would not reveal which of Hergé's stories will be included.

"I'm not going to say which stories have been chosen for Peter Jackson's sequel because Peter and I agreed that we weren't going to let that information out yet. The script is now being written. It's more than one book, but it's not three books, so that means it's two books. It's two and a half books that we're combining with The Secret of the Unicorn. And Peter will start working on the film this year. When he's done shooting The Hobbit, he'll begin his performance capture work with the actors later in 2012, which I'm very excited about. And of course, I'm hoping I'll be able to direct the third one. I'd love to do the third one because I had so much fun on the first one."
