Gunfire and mushroom clouds visible just off Airline Highway have confused passing drivers for more than a month now.Patrick Mulhearn said these choreographed explosions are a sign of economic growth for his studio and the film industry in the state.Mulhearn is the director of studio operations for Raleigh Studios Baton Rouge at the Celtic Media Center, which is hosting the filming of “Battle: Los Angeles.””Battle: Los Angeles” is a post-apocalyptic war movie following a group of marines on their mission to extract civilians from Santa Monica, said Tommy Harper, Unit Production Manager in charge of the budget, staffing and managing the daily administration of the film.The movie is one of about 21 projects currently filming in Louisiana and one of three projects filming in Baton Rouge, said Chris Stelly, director of film and television for the Office of Entertainment Industry within Louisiana Economic Development.Stelly said the total number of films for the state is going to be lower than last year, which saw about 80 productions.”We were competing with the actors strike earlier this year, the downturn of the economy and reaffirming the commitment to the tax credits because they were scheduled to scale back at the beginning of next year,” Stelly said.Stelly explained this summer the legislature reaffirmed the state’s commitment to the film industry by increasing tax credits for film by 5 percent and making the incentives indefinite.The tax credits now stand at 30 percent with an additional 5 percent for hiring Louisiana labor.”We have seen a steady increase in activity since the end of the session, and quite honestly, it has been going strong ever since,” Stelly said. “We are looking to end the year strong, but we are looking at a 2010 that is going to be record-breaking.”Stelly said the interest in filming in the state points to a record-breaking 2010.The Warner Brothers film “The Green Lantern” is the largest-budget film scheduled to shoot in Louisiana in 2010 so far.Just off Airline Highway is the 23-acre Celtic Media Complex, which is currently the heart of film in Baton Rouge and the largest film studio in the state.The media center — originally meant to be Master P’s production studio — boasts five studio stages ranging up to 30,000-square feet that can provide a quiet, climate-controlled set for films like “Battle: Los Angeles” to build massive filming sets to shoot on. Harper said the combination of tax incentives, the state’s film commission and the quality of facilities in the state made Louisiana more attractive than Georgia and New Mexico when “Battle: Los Angeles” was scouting filming locations.”The state has great prospects,” Harper said. “You have the tax incentives that are strong here, and each year the crews are becoming deeper and deeper. You can get equipment here, you can get grip and lighting, you can get trailers, you can get everything you need here. So you guys are on the right path.”Louisiana was boasting about $10 million in film production per year before the inception of the tax incentive program in 2002 for films, Mulhearn said.Since then, the film industry has seen more than $2 billion in project investment with about $1.5 billion being left in the state, Stelly said.”To be honest, had the legislature not upped it and made it permanent, there is a good chance this place would be sitting empty right now,” Mulhearn said. “But now there is a sense of permanency, and we are seeing more and more people uprooting themselves from California and moving here.”- – – -Contact Xerxes A.
