I would love to see Get Smart as well. However getting cast and crew involvement at this point is a long shot.
Mel Brooks is still quite busy milking the "The Producers" gravy train (upcoming movie in the works). Don Adams is battling health problems plus his daughter's own potentially terminal illness.
There was a "Get Smart" reunion of sorts late last year that I stumbled across one day. If you go to this
page you'll be treated to some nice pictures of the cast. I was particularly happy to see a pic of William Schallert, one of my favorite TV character actors. Barbara Feldon still looks very pretty (she's in her 70's!). Don looks quite frail.
