The filming of movie action sequences has been restricted by authorities in Paris following last month’s attacks in the French capital. “There’s a problem with these action-type scenes, as the actors in uniform could be targets for terrorists,” said police commander Sylvie Barnaud. “Also, the actors could pose confusion for the general public – during this highly sensitive period.” She said the use of fake weapons and pyrotechnic effects were also banned. Tensions remain high following the attacks in January which left 20 people dead, including three gunmen. Armed police and soldiers continue to guard sensitive sites, including synagogues, media offices and large shopping areas. Paris is a popular destination for film-makers, with its wide boulevards and dramatic landmarks such as the Eiffel Tower and Louvre pyramid. Official statistics provided by city authorities showed there were 930 film shoots in Paris last year, including approximately 20 international productions.
It’s not known how long the restrictions will be in place.
