MGM chief operating officer Rick Sands talked about “Terminator 4” and “The Hobbit” while at ShowEast this week reports Slashfilm.Sands says that T4 will have a new title and not a number, going with the recent poll which confirms moviegoers prefer new titles over numbers. As for someone else taking over for Arnie – “It’s like the ‘Batman’ or ‘Superman’ franchise in that it lends itself to having different actors in the roles”.Sands also confirmed that talks are underway with New Line Cinema to obtain the rights to produce TWO prequel films to “The Lord of the Rings”, based on J.R.R. Tolkien’s “The Hobbit”.

I do hope it does go off with The Hobbit. It would be interesting to see how that is pulled of. With T4 Arnie will never act in it as long as he is the Governer of California.
