No, Harry Potter was actually Romanian
According to Variety, "The U.K. Film Council is lobbying for the tax credit, which takes effect in April, to deliver a 15%-20% benefit for big-budget movies." And those numbers reflect spending 80% of the budget in the UK; anything less results in less tax credits. Films budgeted below 35% will see more credits available, but still less than previously expected, based on Olswang's analysis.
It is possible that Hollywood-financed UK characters such as James Bond and Harry Potter will find themselves filming in foreign lands.
