People You Forgot Guest Starred on ER
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.

On the third episode of ER’s 10th season, a lot is going on, but almost lost in all of the action if you don’t play close attention is a very young Zac Efron, who dies on the operation table.

Role: Darnel Smith
In the 12th episode of season six, Shia has a guest appearance as a boy who is in the hospital after getting in a fight at school. Shia’s character Darnel has muscular dystrophy, and you might just be blown away by LaBeouf’s performance. He does so well in one particular scene that involves tears, it might just coax some out of your own eyes.- 1Disturbia175 Votes

Dunst was in multiple season three episodes, first appearing in the fifth episode as a street youth who meets Dr. Ross and Nurse Hathaway on a mobile health van that goes to County General when Southside closes. She has an infant with her and claims to be the baby's mother, but it’s evident she’s lying. It turns out the infant needs surgical treatment, but she disappears and Ross can’t find her. She doesn’t return until five episodes later, on “Homeless for the Holidays,” and she would appear three times after than, concluding her story arc on the 22nd episode, “One More for the Road.

Role: David Kerstetter
Scott appeared on this season one episode in one of his first acting jobs ever. Scott has said he can recall seeing George Clooney, who was a massively rising star at the time, playing basketball with guys on the set. This was his sole appearance on the show and it would be many years before he found his way to Parks & Recreation, though he was on Boy Meets World as well during the 90s.- 1Step Brothers31 Votes
