The Film Commission has warned film-makers it may have to cut back further on the number of films it helps finance as it wrestles with static Government funding and a drop in income from other sources.
The commission's statement of intent said funding from sources such as the Lottery Grants Board and income from films had dropped significantly in the global recession.
Private investment in films had also slumped since 2008, making it hard to get movies off the ground.
The commission said it aimed to fund four substantial feature films a year, but that was in jeopardy and a Government review of the screen sector could mean worse news. It had used reserves to cover deficits so far, but those would be exhausted by 2014-15.
"Without additional funding sources, we anticipate a decrease in the number of feature films we can support." The maximum amount put towards any one film was cut from $2.5 million to $2 million in September 2011 to stretch funds and "encourage film-makers to find other funding sources to supplement ours".
