'Downton Abbey's' Shirley MacLaine: Maggie Smith is 'so much fun'
"Amazing day on Downton Abbey set. I love the British humor and temperament and functionality. Maggie is so subtle and so much fun!" tweets MacLaine.
However, don't go checking MacLaine's Twitter account for these tweets - she has deleted them. Weird. But we saw them and we're glad she's having such a good time so far. We're very much looking forward to our first sneak peek of her as Martha.
"Downton Abbey" returns to the U.S. airwaves in January 2013.
