George Clooney doesn't look anything like Steve Jobs, but you've got to believe that with today's makeup and technology, anything is possible. The thing is, it's not really important that he would look like him as long as he'll portray his character right and make us feel that he is him. And let me tell you, George Clooney is one of the best actors in Hollywood and I enjoyed every movie I watched for him. His roles in the Ocean trilogy were amazing.
Have you watched his 2009 movie Up in the Air? I'm not a fan of drama but it was one that I enjoyed from the start to the finish.
Anyway my point is, if anyone deserves to play Steve Jobs on television, George Clooney is definitely not one to overlook.
