Prime Minister David Cameron has pledged to continue to back high-end film and TV tax credit breaks, claiming that they are “working so well”.

Speaking at Wednesday’s Prime Minister Question Time the Prime Minister said: “The British studios are full to bursting point making these movies … we need to go on backing these movies, that’s why…the Chancellor … is continuing to back the film and television tax credits that are working so well.

Cameron was speaking after Conservative MP Tobias Ellwood highlighted the role played by Bournemouth University in Gravity’s Oscar victory.

Around 50 Bournemouth students worked on Alfonso Cuaron’s sci-fi thriller in partnership with London special effects house Framestore.

“Bournemouth University does have excellent courses that have helped to build up the British post-production industry and helped create these firms,” he added.

Culture secretary Maria Miller added that the British film, television and gaming industries were worth £8m an hour to the UK economy.

The high-end television tax breaks, which launched in April 2013, have brought £150m of foreign investment according to figures from the British Film Institute.

Series such as CBS drama Elementary and HBO’s Game of Thrones are among the 30 shows to have qualified for the tax break to date, alongside US shows including By Any Means and Fortitude.
