The eighth annual ATX Television Festival has added panels for “One Day at a Time,” “Veronica Mars,” “Into the Dark: Culture Shock” and “Letterkenny” to its lineup, Variety has learned exclusively.

Additionally, Beau Willimon (“House of Cards,” “The First”) will return to host his own discussion event and join a panel about playwrights moving to the small screen medium.

Heading down to Austin, Texas for the “One Day at a Time” panel this year will be executive producer Mike Royce and cast members Justina Machado, Isabella Gomez, Todd Grinnell and Stephen Tobolowsky. This marks Machado and Gomez’ second consecutive years with the show at the festival, as the 2017 event also featured a panel discussion for the series. “One Day at a Time,” a reboot of the classic family sitcom of the same name, was produced by Sony Pictures Television and ran for three seasons on Netflix. It was also executive produced by Norman Lear and Gloria Calderon Kellett.

Hulu is coming to the festival in a big way, this year, as well, with both the “Veronica Mars” revival and and early look at the July installment of Blumhouse Television’s “Into The Dark.” While panelists for the “Veronica Mars” panel are still to be announced, co-writer and director Gigi Saul Guerrero will be on hand to participate in a discussion about “Culture Shock,” which is a dystopian horror film following a young Mexican woman who crosses illegally into the United States in pursuit of the American Dream but finds herself in “an American nightmare.” Additional panelists for “Culture Shock” will be announced at a later date. This panel is in addition to the Blumhouse Television panel that was previously announced.

Canadian comedy “Letterkenny,” from creator and star Jared Keeso, will present a panel featuring executive producer Mark Montefiore; executive producer, director and cast member Jacob Tierney; and cast members Nathan Dales, Michelle Mylett and K. Trevor Wilson. The show, which was renewed for four seasons at the end of 2018, is also part of the Hulu family in the U.S. The hockey-centric show focuses on the “dustups” Wayne (Keeso) and his friends find themselves in with small-town rivals.

And Willimon is planning another “intimate, interactive” panel. Past Willimon experiences have included him inviting members of the audience up on the panel with him for an impromptu Q&A, as well as discussing biggest fears and the expansiveness of the universe, as well as his creative process.

Willimon has also been added to the “A Playwright Walks Into a Writers’ Room” panel, which will feature writers and executive producers who made the transition from stage to screen. Other panelists here include “Vida” creator and showrunner Tanya Saracho and Bad Robot’s senior vice president of television Rachel Rusch. Additional panelists will be announced at a later date.

The eighth annual ATX Television Festival takes place June 6-9, 2019. Other previously announced panels include reunions for “Men In Trees” and “Greek”; the aforementioned Blumhouse Television break down; new series such as Showtime’s “City on a Hill,” “Dare Me, “Alternatino with Arturo Castro” and “Perpetual Grace Ltd”; and themed panels including the “Presidents of the Guilds,” “Inside the Writers’ Room” and “The Power of Female Partnerships.”
