Michael Imperioli 
played Christopher Moltisanti, Tony Soprano's nephew, on the HBO series The Sopranos for which he has won a Best Supporting Actor EMMY. Earlier today, "an unexpected jewel-box (small bomb)that was built to house progressive new plays" blasted outside of Michael Imperioli's Studio Dante, damaging a van but causing no serious injuries. New York police are currently investigating the incident and Mayor Michael Bloomberg was certain to announce "there is no evidence that this was terrorism".
