The British leader is rolling out a series of austerity measures in a bid to slash Britain's debts and shore up the crumbling economy, and budgets for music and movie projects are facing severe reductions.
The UK Film Council, set up in 2000 to develop and promote Britain's movie industry, was shut down in 2011 and now funding for arts education in schools will also be cut, but Whishaw is adamant officials in his native country should work to preserve artistic endeavours.
He tells Britain's Live magazine, "I think it's awful. But I think it's also something that's not new. I suppose I find it baffling that people in government don't see the value in it. We're not just numbers in an economic system, there are other things that people need...
"There is a weird mentality towards the arts in this country. I wish that the arts were better supported, and you can't say that enough times, but I also believe that whatever happens, artists will keep going. To a degree, there is nothing wrong with having to struggle and fight a bit, but I wouldn't want to suggest that this should be a valid method for an arts policy."
