HBO's High Maintenance co-creator Ben Sinclair has something up his sleeve. (And it's not just weed.)

Hollywood Reporter reports Sinclair is teaming up with cannabis journalist Abdullah Saeed to make an "untitled prison dance movie." The two will co-write the film together, but Sinclair will take a shot at his first ever full-length directing gig.

Given the concept's incorporation of dance, the project will echo the style of a musical.

Sinclair has directed episodes of High Maintenance, but in its recently wrapped second season only co-directed three, alongside his co-creator/ex-wife Katja Blichfeld.

In addition to starring in the road trip series Vice Does America, Saeed produces and hosts Viceland's marijuana food show Bong Appétitwith episodes featuring chefs like a 91-year-old grandmother. According to Variety, the series—which has a different theme for each episode, from watermelon bongs to a Shabbat dinner to Greek-inspired doughnuts—was nominated for a James Beard award in the television category.

Sinclair and Saeed will work with producer Arnon Milchan of New Regency. Fox Searchlight will act as the film's distributor.

There aren't any further details of what the musical will entail or as to who is in charge of the music, but there's one detail we can probably safely predict: there will be marijuana involved.
