As television series go, "Gilmore Girls," "ER" and "Mad Men," don't have all that much in common. But what they all do have, at some point over the course of their runs, are episodes directed by Lesli Linka Glatter. Though the nature of TV directing means viewers likely don't associate her name with the series she's worked on (save for maybe "Homeland" and "The Leftovers," for which she also serves as co-executive producer), Glatter has directed some of the most notable television episodes, spanning a diverse array of series, of the past two decades.
