The entire premise of the “Speakeasy” web series is for Paul F. Tompkins to share beverages of the alcoholic variety with other famous people. But that’s a bit tough for Summer Glau — she’s eight months pregnant. So instead of downing vodka cranberries, hold the cranberries, they discuss all things Firefly, Terminator: The Sarah Connor Chronicles, and dancing over Shirley Temples. Oddly, despite Glau being such a nerd icon, Tompkins never brought up the Star Wars ball droid, though he did ask her to imitate popular animal memes.
