More Minions. More Gru. And now there’s Dru, too. It’s a family affair in the second trailer for Despicable Me 3, starring the voices of Steve Carrell (as both Gru and Dru), Kristen Wiig, Trey Parker, and Miranda Cosgrove. DM3, another likely surefire hit from Illumination Entertainment, opens this summer for the long 4th of July weekend on June 30, 2017.
