'Downton Abbey's' famous fans: Patton Oswalt, Kristen Bell and more

Sure, plenty of us have been swept away in the glitz, glamor and intrigue of "Downton Abbey" on PBS Masterpiece. But did you also know there are more than a few famous faces who can be counted amongst the fans of the British show.

Patton Oswalt is certainly the most vocal. He dressed up for a viewing party and he also hilariously live-tweets each weekly episode, including such gems as:

• "I can't Tweet this enough: I love Maggie Smith. #DowntonPBS"
• "Ouija board! This was the closest thing to Twitter at Downton. #DowntonPBS"
• "Maggie Smith refuses sauce like a GANGSTA! #DowntonPBS"
• "O SHOES in front of the Dowager Countess? Why don't you just whip your Johnson out and sing, "Danny Boy"? #DowntonPBS"
  

Other famous fans of "Downton" include Kristen Bell ("you guessed it, its 130am and im re-watching Downton Abbey episodes. I am wildly obsessed with this show"), Josh Charles ("While suspended, maybe Will should head across the pond and defend John Bates on appeal. What do you think? #DowntonAbbeyGoodWifeCrossover") and of course, we've already told you how David Boreanaz of "Bones" is angling for a guest-starring role.
