Wikipedia:Articles for deletion/List of guest stars of ER (TV series)
Personally, I'd move a bunch of the Cast, Supporting Cast, and this into a new List of ER characters article. For 13 seasons (about 8 of which I watched ...) it's a pretty thin and listy article. The guest stars, certainly, don't need their own, but  would suggest that one comprehensive list would be a good sidebar to the main article
