Nominated for 25 Golden Globes and 110 Emmys, including 7 for Outstanding Drama Series, ER has long been one of the best prime-time shows on television. Premiering in September 1994 on NBC, the hour-long hospital drama vividly illustrates the intensity and fast-paced stress endemic to hospital emergency rooms across America. Brought into being by Michael Crichton - famous Hollywood insider, novelist, and brains behind such films as Jurassic Park, Twister, and Timeline - ER fulfills its creator's ultimate vision (it took over a decade of pitching the show before network executives bit) for a close-to-life glimpse of the technology and the humanity omnipresent in the ER. Since its inception, many cast members have passed through the halls of ER, many of them having gone on to become big stars in Hollywood

ER follows the exploits of a group of emergency room staff who work in a busy Chicago hospital. The show attempts to examine every detail of the ER experience. From the exhilaration of saving a life to the tedium caused by mountains of paperwork, all the highs and lows are covered. In the show's first year, a number of regular faces staffed the ER. Doctors Mark Greene (Anthony Edwards), Peter Benton (Eriq La Salle), Douglas Ross (George Clooney), and Susan Lewis (Sherri Stringfield) were regulars in the ER along with Head Nurse Carol Hathaway (Julianna Margulies) and Benton's medical student understudy (and later ER doctor), John Carter (Noah Wyle) Any given episode tends to run multiple plot lines throughout the show, interweaving scenes in short snippets intended to heighten audience emotion and create the aura of a stress-laden atmosphere. The show's high drama, coupled with subplots of the staffers' personal lives and the display of cutting edge medical technology, combine to make ER one of most adrenaline-inducing programs in television history

The ER (Season 4) DVD features a number of dramatic episodes including the season premiere "Ambush" in which the ER is put in the spotlight when it's chosen as the site for the filming of television documentary. Trauma specialist Elizabeth Corday (Alex Kingston) joins the staff of the ER while Carter begins his residency. Meanwhile, the usual tragic cases pour into the ER, such as a man left paralyzed after trying to break up a gangland fight Other notable episodes from Season 4 include "Fathers and Sons" in which Doug travels to California to settle his father's estate while Mark goes with him to visit his San Diego family for the first time in years, and "A Bloody Mess" in which Dr. Corday performs an experimental procedure on a patient without getting the required permissions first
