Tom Gustafson and Cory James Krueckeberg are also the team behind the acclaimed indie musical film "Were the World Mine," which put a gay twist on A Midsummer Night's Dream.
They describe "Mariachi Gringo" as a celebration and exploration of Mexican culture. The film includes 15 musical numbers.
"X-Man" actor Shawn Ashmore leads a cast that also features Dunagan (August: Osage County), Burton (The Constant Wife), Wopat (Catch Me If You Can), Keenan-Bolger (Spelling Bee), Downs (Like Water for Chocolate) and Martha Higareda ("Te Presento A Laura").
Gustafson directed the film, which "follows a small-town mid-western man (Ashmore) as he runs away from his family and journeys to Mexico to follow his dream of being a mariachi," according to Krueckeberg.
Kreuckeberg also told Playbill.com that he and Gustafson are working to enlist a current Broadway songwriting team to pen the soundtrack for their upcoming movie musical project.
