But what female comic would play such a role? With her glasses and inescapable nerdiness, Tina Fey is like a female cross between Egon Spengler and Louis Tully (who was made a deputy 'Buster in Ghostbusters 2). And before she was on SNL, Amy Poehler used to dress up in a uniform and investigate the unusual with three similarly dressed dudes as part of the Upright Citizens Brigade, so she'd fit right in! But since the movie is being written by The Office's Gene Stupnitsky and Lee Eisenberg, why not get Jenna Fischer (Pam), Angela Kinsey (Angela) or Kate Flannery (Meredith) to strap on the pack? Or better yet, all three, and it can be like Charlie's Angels, with Bill Murray in the Bosley role! Wait -- scratch that, and just check out Bill's interview below.
