Unless, like me, your typing fingers turn into thumbs around brainy, sexy women, this Sunday August 6th at 9 p.m. Eastern you can join BuddyTV for a live chat with Jacqueline McKenzie -- NTAC Agent Diana Skouris -- on The 4400.

McKenzie also recently appeared as the wife of one of the William H. Macy's characters in the Nightmares and Dreamscapes episode: Umney's Last Case. You can ask her how she likes Vancouver, or whether she thinks the writers will give her a new romantic interest, now that she's dumped the kind-but-unsuitable Marco (I think Agent Diana prefers badder boys).
