Critics say the bill would gut the film industry because the changes would give companies credits instead of cash back.
Lee Hill attended the rally on Saturday even though she doesn't work in the film industry. Hill says if the bill passes, production companies would target other areas. "They would go to South Carolina, Louisiana, or Georgia," said Hill. "They would take all this extra income out of our area."
Many political figures from across the state were also on hand including Mayor Bill Saffo.
"Here we have an industry that's thriving, it's growing and making world class films," said Saffo. "Why would we want to take that away? It's crazy."
Protestors plan to keep fighting this bill as it makes it way through legislation.
Meanwhile, Saffo says the City of Wilmington plans to pass a resolution in support of the current film incentives program. County Commissioner Beth Dawson says the county plans to do the same.
