Throughout the years H:LotS has had its share of notable guest appearances including Robin Williams, Bruce Campbell, Elijah Wood, Chris Rock, Jake Gyllenhaal, Tim Russert, James Earl Jones, Jay Leno, Terry O'Quinn, Steve Buscemi, etc. (that's just off the top of my head!)
So, who is your favorite guest star?
My favorite is Lily Tomlin as Rose in "The Hat". Her performance in the episode is very entertaining, endearing even; she really creates a believable character. Also, this episode nicely illustrates the Lewis/Kellerman partnership, which I'm quite fond of. The trip to the Enchanted Forest is priceless!
