Massachusetts native John Slattery was in Boston last night to toast his appearance on the cover of Boston Common magazine. He made the scene with his preteen son, Henry Harry, and his wife, Talia Balsam (who plays Roger Sterling’s aggrieved ex, Mona, on the show). Grub Street hunted down the sweaty — yet suave! — silver fox on the magazine’s 100-degree red carpet, where he discussed his teetotaling on-set ways.
We of course, wanted to know if he could whip up a decent Gibson, given that it’s Roger Sterling’s beverage of choice. Slattery, however, is less enamored of the drink in real life: “Isn’t that just a martini with onions in it?” he asked us. Well, yeah, but we were hoping some role research would have meant Slattery gleaned a few martini-making tips over the years. Sadly, that’s not the case. “The ‘Gibsons’ I usually get are actually water and onions,” he tells Grub Street. “It’s five or six in the morning — they’re not giving us real booze.”
