John Carney is closing out the Dublin Film Festival with a crowd-pleaser. His new movie Power Ballad, starring Paul Rudd and Nick Jonas, will debut as a world premiere on March 1 at Dublin’s Bord Gáis Energy Theatre — and both stars will be in the house. The film pairs Rudd as Rick, a wedding singer well past his glory days, with Jonas as Danny, a former boy-band heartthrob sliding out of the spotlight. A random gig, a late-night jam session, and some musical bonding spark an unlikely friendship — until they head back to their real lives and realize that one night has completely scrambled both their futures. After Dublin, Power Ballad heads to SXSW before Lionsgate rolls it into theaters on June 5. The cast also includes Marcella Plunkett, Havana Rose Liu, and Jack Reynor.
