Here's the trailer for Why Stop Now, the upcoming movie chronicling Eisenberg as a piano prodigy attempting to get his mother (Melissa Leo) into rehab the same day as his audition for a prestigious music institute. Things don't go as planned, however, when the pair get involved with the mother's drug dealer (played by Tracy Morgan). Safe to say that hijinks will ensue, although, if the trailer is to be believed, it looks like the film may show a slightly more nuanced side to Morgan than what we've seen in the past.
