An inquiry into UK-originated film and television content is being launched by the House of Lords communications committee.
The move comes as a result of criticism of the film tax credit introduced two years ago, the Financial Times reports.
Its effectiveness and the impact it has had on UK television content is to be assessed, along with the role of the government film agency, the UK Film Council.
Figures from the council reveal that UK films produced with one of its treaty partners have dropped from 52 in 2006 to 29 in 2007.
