WARNING: SPOILERS ahead for Hacks season 4, episode 4.
Merrill Markoe’s cameo inHacksseason 4, episode 4, “I Love LA”, honors her legacy as a legendary comedy writer that dates even farther back than working onLate Night with David Letterman. Markoe is one of several notableguest stars inHacksseason 4, along with Carol Burnett, Helen Hunt, and Randy Newman. Her appearance inHacksseason 4, episode 4 asDeborah fulfills her lifelong dream of hosting a coveted late-night show– years after she was robbed of the opportunity – is certainly no coincidence.
Markoe’s cameo involves a conversation in a workplace snack room with Ava Daniels, the self-imposed via blackmail (but well-deserved) head writer of Deborah’s late-night show. While Ava is just a fictional character inHacks,Markoe is the real deal when it comes to late-night legacy, especially considering she rose to prominence in the 1970s and 1980s when women faced much more difficult obstacles and uphill battles in the entertainment industry.

She Also Dated Letterman For 10 Years From 1978 To 1988
Markoe was the head writer onLate Night with David Lettermanfrom 1982 to 1986, which earned herthree Emmy Awards for Outstanding Writing in a Variety or Music Program. Markoe and Letterman were also romantically involved from 1978 to 1988. Although Markoe’s claim to fame was becoming Letterman’s first head writer and helping him become a household name that landed him his decade-spanningLate Show, her career started even before that landmark position.
Markoe’sHacksseason 4 cameo mainly focuses on her Letterman history butshe was also involved in one of the first female-led variety shows,Mary, starring Mary Tyler Moore. Markoe was actually a cast member on the 1978 variety show, although it was canceled after just 3 episodes. Variety shows likeMarywere quite similar to the late-night shows we often see today, so Markoe’s crucial role in it is significant to a huge theme inHacksof the history of women in late-night and TV hosting roles.
