George Clooney doesn't think an 'E.R.' reboot would fare as well as the original series. The 59-year-old actor became a household name after playing Dr. Doug Ross for 15 seasons on the medical drama - which ran from 1994 to 2009 - but suggested he wouldn't be up for reprising the role if the show was to return to screens because he's unconvinced it could match the consistent quality displayed in the programme's original run. Asked about the possibility during a live virtual reunion of the ER cast on Stars in the House to support co-star Gloria Reuben's non-profit organisation, Waterkeeper Alliance, he said: "I don't know. The hardest part is that when you look at the show and consistently over so many years â it would be hard to say that you could do it at the level that we did it. I'm not sure that that's available."
