Directed by Matt Walsh, a co-founding member of the world-renowned comedy troupe Upright Citizens Brigade, the entirely improvised comedy High Road tells the story of Glenn “Fitz” Fitzgerald (James F. Pumphrey), a young man whose loyalties are split among his band, his girlfriend Monica (Saturday Night Live’s Abby Elliott), and selling weed. When one of his drug deals goes awry, Fitz and 16-year-old neighborhood kid Jimmy (Teen Wolf’s Dylan O’Brien) hit the road together. Amid car chases, guns and a suspicious doctor (Horatio Sanz), Fitz has to navigate their way to safety. The film also stars Lizzy Caplan (New Girl, True Blood, Party Down), Ed Helms (The Hangover 1 & 2), Rob Riggle (21 Jump Street), Joe Lo Truglio (Wanderlust) and Zach Woods (The Office).

During this interview, conducted at an audio commentary recording session for the DVD/Blu-ray, director Matt Walsh and actor Horatio Sanz talked about how the film was always intended to be a low-budget passion project, the challenges of keeping a totally improvised movie on track, shooting in a creepy old hospital in downtown Los Angeles, that the improvisational films of Christopher Guest and Zak Penn were an inspiration for this one, and how there will be a fair amount of extras included on the DVD/Blu-ray.

A trailer is now available for High Road, the fully-improvised comedy by director Matt Walsh (The Hangover). Cast with a ridiculous number of improv comedians at all different levels of fame, High Road stars relative unknowns in the principal roles. James F. Pumphrey (Players) is Fitz, a well-meaning drug-dealer who hits the road to escape his problems and encounters some strange characters along the way. The strong supporting cast features Ed Helms, Rob Riggle, Horatio Sans, Kyle Gass, Abby Elliott, Lizzy Caplan and Zach Woods. While it plays like a mash-up of Harold and Kumar and Pineapple Express, I can’t quite figure out if it’s destined to be a cult classic or a simple misfire. Hit the jump to check out the trailer for High Road.
