Nick Lachey. He’s dreamy.
Jessica must stay home. and clean. Yeah right.
Well, my first choice is a non-American too: Emma Thompson, who is alleged to be extremely fun to be around.
But sticking to my own shores, I’d have to say…Hmmmm… who would be fun to talk with? Oh, I know! Harvey Fierstein!
Hmm, probably Ted from Queer Eye because he’d cook a great meal, provide intelligent conversation, and then put out for dessert.

I would like to make a home movie of the dinner with my guests Bill Bryson, PJ O’Rourke, Hunter S. Thompson, Dave Berry and (just to throw a woman into the mix for laughs) Pentagon Spokeswoman Victoria Clarke. . .They would all have such fun with her in their different ways :wally
. . . and Christopher Nolan would direct the home movie - all out of sequence, of course 
Male: Alan Rickman, for the reasons mentioned above.
Female: Margaret Thatcher. The major political figure bar none in post-Churchill Britain.
