Melissa Leo, Christoph Waltz, Forest Whitaker and Tom Hooper are among attendees expected at the Ischia Global Film and Music Festival, which has also recruited a robust lineup of industry heavyweights.

Informal extravaganza on the Italo isle will fete Recording Academy prexy Neil Portnow and helmer Kenny Ortega with nods.

Paula Wagner, Rick Nicita, Avi Lerner, Mark Canton and Heidi Jo Markel are among Hollywood producers announced for Ischia’s Global Production Summit, along with a host of Italo execs including Aurelio De Laurentiis, Fulvio and Federica Lucisano, and RAI Cinema topper Paolo Del Brocco.

The lineup will include Italian launches of John Madden actioner “The Debt,” docu “The Bully Project,” helmed by Lee Hirsch, and a 15-minute sneak preview of Joel Schumacher’s “Trespass,” starring Nicole Kidman and Nicolas Cage.

Eight-day fest, headed by Pascal Vicedomini, who also tops sister event Capri Hollywood, kicks off on Sunday.
