The bill that would have raised the tax credits for film and TV productions shot in Hawaii has stalled in the Hawaiian legislature and with it plans to build two movie studios, on the Islands of Oahu and Maui. The bill would have boosted tax credits on films shot in Oahu to 35 percent from 30 percent and on films shot in any of the other islands to 40 percent. The inaction by the legislature would also appear to undermine a $400-million studio project by Relativity Media and the Shangri-La investors group that was hinged to passage of the bill.
