Noah Wyle -- the last of remaining original cast member still on the NBC drama ER -- says he too is ready to go.
But not until after next season.
"I think most actors are born with a drop of gypsy blood in that they like to be jacks-of-all-trades but masters of none," Wyle tells TV Guide. "And I've been sort of a master of this one trade for a very long time. So the need to do something different is definitely growing within me."
Wyle's Dr. John Carter and Sherry Stringfield's Dr. Susan Lewis are the only two remaining ER cast members from the original season -- but Stringfield left the show for five years before returning.
That makes Wyle the only constant ER character from when the show debuted in 1994 -- and it sounds like he's tiring of the role and has grown disappointed in the storylines that have been given to Carter.
"[Carter] is the utility player that you can plug into anybody else's storyline as a reactive character or a sympathetic character to allow the audience to see through his eyes," says Wyle, 31.
Over the years, Carter has been stabbed and developed a drug habit -- all while withstanding the slings and arrows of his grumpy mentor, Dr. Peter Benton (Eriq LaSalle).
ER, which for years was TV's top-rated drama, was surpassed last year by CSI -- which continues to go great guns for CBS on Thursday night.
Most of last season on ER was spent on the slow, agonizing death of Dr. Mark Greene (Anthony Edwards), who died in the season finale last May (marking the departure of yet another ER original).
ER executive producer Jack Orman tells TV Guide that the show will be more exciting this season.
ER, says Orman, will return "to the franchise, which is doctors as heroes surviving the environment."
