You can't film here this is bat country...
Despite getting a permit for the location in Bulgaria the authorities are fining the production team for taking down trees outside a cave that houses a number of endangered bat species.
The fine is not yet set but will be between $343 and $3,440, which lets be honest is pocket change to these people.
The production of Expendables 2 looks plagued with problems at the moment following a stunt mans death on set last month, but I suppose any publicity is good publicity right?
