In an interview with SciFi Wire, Nick Stahl, who played the role of John Conner in "Terminator 3," revealed that neither he nor Claire Danes will return for the fourth "Terminator" movie. "None of the cast is coming back," he said. As for the reason, he surmised that it might have something to do with the fact the story will take place further in the future and that his character will be "quite a bit older." Nick Stahl can be seen in the upcoming movie "Sin City," which is opening April 1st.
