One of the most loved and talked about bloopers on YouTube character breakthrough appeared in Season 3 of “ER”. George Clooney’s Dr. Ross talking to Dr. Greene and Dr. Maggie Doyle (Jorja fox, fox) about how she was hiding Dr. Ross for the day the slip happened.
Dr. Greene told the new Dr. Doyle that she was going to follow Dr. Ross around. Dr Doyle replied: “I am handling my own cases on the Southside. “That’s right, this is your first date and I want you to stick with George,” Greene said, inadvertently saying the wrong name. “Doug…George Clooney, plays Doug Ross,” he added. In response, Clooney looked into the camera and said, “I’m Doug and I’m Batman.”
By the time of the blooper, Clooney was getting ready to appear as the Caped Crusader in 1997’s “Batman & Robin.” YouTubers pointed out how surprisingly happy he looks set to take on the role, despite years of interviews saying he hates it. One YouTube commenter joked: “Looking back, I wouldn’t brag about it, George.”
