ER had a brilliant run that lasted 15 seasons and 331 total episodes from 1994-2009. The show had its fair share of successful actors and actresses in the main cast, including George Clooney, Mekhi Phifer, and Noah Wyle, to name a few. Along the way, there was also plenty of famous people on ER making cameos and guest appearances throughout the years. Now, years removed from the series, with so many episodes in the foggy part of your memory bank, it’s quite a surprise to see some of the stars who had guest appearances on ER.
