France has been forced to swallow its linguistic pride by pledging to change the law to keep Europe's most expensive film production on home soil, because it is in English.
Valerian and the City of a Thousand Planets, a science-fiction blockbuster starring American Dane DeHaan, 23-year-old British model Cara Delevingne and Britain's Clive Owen, was due to start shooting outside Paris early next year. With an estimated budget of €170 million (NZD $304M), it will be the costliest film ever made in mainland Europe.
However, in a coup de theatre late last month, director and co-producer Luc Besson - whose past hits include Lucy, starring Scarlett Johansson, The Fifth Element, and the Taken and Transporter movie franchises - announced he was moving it to Hungary.
Besson, who has raised eyebrows in France for living and paying tax in the US, said he had little option but to drop his native country because current legislation meant the film was not entitled to generous tax breaks only granted to films shot in French.
"There's a small problem called tax credits... I have a French film being made in English so I have the right to zero (credits) as a French film," Besson told radio station RTL radio.
