No, unfortunately it’s not another stoner comedy.  From Variety:

 James Franco is joining Danny McBride in “Your Highness,” the Universal Pictures comedy to be directed by David Gordon Green.

Scripted by McBride and Ben Best, the comedy follows two spoiled and arrogant princes in a medieval fantasy setting. When an evil wizard casts a spell on their father and kidnaps the older prince’s fiance, they’re forced to go on a quest to save their family and the kingdom.

Franco was legendary as Saul Silver, and as far as I’m concerned, Danny McBride is batting 1.000 in his professional comedic career.  The guy has been funny in everything he’s been in” Hot Rod, The Heartbreak Kid, Tropic Thunder, Pineapple Express, and recently, Eastbound and Down.  With Franco and a medieval setting, I’m guessing McBride will deliver again.
