Sam Neill will not be involved in Jurassic Park IV, according to LA Daily News.

"I know nothing about it. I haven't heard from anyone," says the actor, who reprised his role as Dr. Alan Grant in Jurassic Park and Jurassic Park III. He adds that any reports that say he is attached to star are false.
