HBO announced earlier this week that the prestige network has ordered six new episodes of the beloved web series High Maintenance. Each of the previous 19 episodes, which starred the show's co-creator Ben Sinclair as an easy-going pot dealer in a Brooklyn full of basket cases, ran about six minutes long. What does it mean to make films for primarily online audiences? What length makes sense? And how does a show like High Maintenance find a following and rise to the level of an HBO project?

We'll hear from Sinclair and his wife and co-creator Katja Blichfeld, along with filmmaker Judd Erlich and ESPN Films' Dan Silver, on this panel, "Long Story Short." Brian Koppelman, screenwriter and host of Slate's podcast "The Moment," moderates.
