Between two ferns has been making people laugh uncomfortably for years on Funny or Die with the fake celebrity talk show hosted by Zach Galifinakis. Now, that web show is becoming a movie, set for release on Netflix, September 20th. In the new film, Galifinakis must make up for the biggest mistake of his career (nearly killing Matthew McConaughey) by filming 10 new episodes all around the country. What happens next looks like a combination road movie/ ultimate Between two ferns episode as an a-list cast that features everyone from Benedict Cumberbatch and Brie to Keanu Reeves and Tessa Thompson.

Zach Galifianakis and his oddball crew take a road trip to complete a series of high-profile celebrity interviews and restore his reputation. Celebrity cameos include: Matthew Mcconaughey, Will Ferrell, Peter Dinklage, Benedict Cumberbatch, Paul Rudd, Tiffany Haddish, Brie Larson, Keanu Reeves, Jon Hamm, David Letterman, Jason Schwartzman, Adam Scott, John Cho, Chance the Rapper, Rashida Jones, Hailee Steinfeld, John Legend, Chrissy Teigen, and Tessa Thompson.
