Batman vs Superman was supposed to be a lead in movie for the new Batman and Superman movies but it now seems to ahve been shelved. If Superman 5 gets off the ground and is a hit and Batman 5 is a hit i wouldnt be suprised though if it ended up getting back on the schedual.
As for Tom Welling he certainly seems to fit the bill more as Superman than most of the names that have been rumoured. Noen of the rumoured names really jump out at me as any good
Ashton Kutcher - Wooden, no chrisma or personality. Can just about pull off the comedic idiot act but thats not Clark Kent./Superman
Kip Pardue - He just doesnt strike me as the right person
Brendan Fraser - Again another Wooden actor who I always think overplays his parts to a point where they often become annoying.
Josh Hartnett - Another actor I find a bit wooden at times and certainly not believable
Jude Law - Doesnt strike me as the man of steel
Paul Walker - Imho was dreaful in Timeline, and the two Fast and Furious movies so on those shouldnt be considered
Matthew Bomer - Dont know a great deal about him but my impression from watching Tru Calling is he just isnt right for the role
Keanu Reeves - Wooden, wtf is up with all these wooden actors being linked with the role, ok I know as Clark he isnt the most charsmatic person but surely you need an actor with a bit of skill
Nicolas Cage - Was 'cast' in the role for a long time and would have made intesting casting but I just dont think it would have worked
Tom welling certainly beats all those hanRAB down imho.
Having said how poor the names linked with the part of supes the Lois lane ones are worse with the likes of Cameron Diaz, Jennifer Lopez, Catherine Zeta-Jones, Jessica Bieland Beyonce Knowles all be linked and none imho being suited for it. The best name linked is Selma Blair who I actually think might very well work.
All of these rumours however are trumped by the fact that Justin Timberlake is tipped to get the role of Jimmy Olsen. WHY OH WHY would anyone cast him in any role, has the world gone mad.
