IFC Films has released the first trailer for Why Stop Now, previously titled Predisposed. The trailer presents a likeable farce about a piano prodigy (Jesse Eisenberg) who needs to check his drug-addict mother (Melissa Leo) into rehab on the day of his audition for a prestigious music program. Things go awry, which draws her drug dealer, Sprinkles (Tracy Morgan), into the quest. Mixed reviews out of Sundance suggest directors Phil Dorling and Ron Nyswaner fail to keep the plot under control throughout the runtime. But I’m intrigued by what I see here, even if the movie only manages to coast on the charms of its eclectic cast.
