Over the past 14 seasons, the halls of ER have seen a multitude of guest stars.  John Leguizamo, Stanley Tucci, Ray Liotta, Forest Whitaker and Hal Holbrook represent just a small sampling of those who have either been on a gurney or had a stethoscope around their neck.

For the show’s 15th - and final - year, NBC will be bringing on another Academy Award nominee to help triage the endless patients.  Waiting to Exhale‘s Angela Bassett will help the veteran series finally come to a close.  While this won’t be her first stint on television (she did have several appearances on my beloved Alias), this will be her first full-time gig on the small screen.

When ER returns next fall, we can also expect a visit from one of the drama’s former staples:  Noah Wyle.  The actor, who hasn’t done much aside from USA’s The Librarian movies, is scheduled to stop by for at least four episodes.
