Over the course of the long run of ER, the show had hundreds of hot actors playing doctors, nurses, patients, family and friends. The actors below were some of my favorites during my recent binge and re-watch of the show. I haven't finished yet, I skipped around a bit, and ignored every episode where Carter was in Africa, but these actors, and their characters, certainly stood out.
Michael Ironside
I've been a fan of Canadian actor Michael Ironside for years. Ironside played Dr William, 'Wild Willy' Swift in the shows first season, as well as two additional appearances in later seasons. I really liked his character on ER, and wished Wild Willy had stuck around. I think given his role, the writers didn't feel he was needed after Laura Innes joined the show as Weaer.
Despite his impressive, and long resume of film and television roles, I believe Ironside's only nude scene scene was this butt view in the 1989 thriller Mindfield. I looked everywhere for a copy of the film, without luck. Finally, I found a copy on Youtube. Thankfully, I also found a slightly better version of Ironside's nude scene thanks to xyzpdq and Scenes from Male Skin.
Paul McCrane
I love actor Paul McCrane, and although he was a total ass hole, also loved his character as Robert, 'Rocket' Romano on ER. McCrane's most notable on-screen nudity occurred in 1994's The Hotel New Hampshire. I enjoyed the film, but LOVED the John Irving novel which I first read when I was in college. I've re-read it once since then, and might pick it up again soon. I love the film versions of most of Irving's novels, but they never fully capture all of the story he manages in his books.
Tom Everett Scott
I've long crushed over actor Tom Everett Scott, and he was great in his brief turn as Abby's brother Eric on ER. I didn't love the character story arc, but Everett Scott did a great job. Sadly, except for a 'sort' of nude scene in An American Werewolf in Paris, the actors most notable nudity came during his run alongside actor Johnny Galeki in the 2006 Broadway play, The Little Dog Laughed.

Chris Pine
Although he had only a couple of lines, and was on screen just a few seconds, I thought it was notable that ER marked the professional acting debut for Chris Pine. I saw Chris discuss his brief appearance with Sally Field on ER on The Graham Norton Show. Sally was also on the show, and didn't really seem to remember their brief moment in the ER together.
Regardless, any excuse to post a couple of my favorite moments of Pine nude on screen. Most of you have seen his brief frontal in 2018's Outlaw King. (Below)
The frontal is fine, but my favorite nude moment of Pine on screen, is the curves and lines of Pine's body in last years All The Old Knives. (below)
