Although it doesn’t look Doug Ross (George Clooney) and Nurse Hathaway will be leaving Seattle anytime soon, long-time watchers of ER will still get a nice surprise this year.

Anthony Edwards, who played Dr. Mark Greene for eight seasons, will be returning to the halls of County General for a brief visit this fall. This cameo will, of course, be a special one considering Greene died of a brain tumor in 2002. It will also be meaningful given the upcoming finale of the entire show.

Edwards’ appearance in a series of flashbacks will help provide “insight into Dr. Banfield’s past.” Dr. Cate Banfield is the new character being played by Oscar-nominee Angela Bassett. The Nov. 13 episode, titled “Heal Thyself.” will also feature other actors from the series’ past.

ER kicks off Thursday, September 25th.
