While shooting certain scenes on London streets, there may be times when road markings, street signs, and light posts can get in the way. It is worth noting that filmmakers can do something about that, but they need to consult someone before doing so.
Once again, the production company must get in touch with the film contact to draw up an agreement if there are specific road signs and markings that need to be removed. This matter must also be discussed with the police.
The highway authority can handle removing the signs. However, the production company will have to pay for removing the signs and putting them back into place once the filming is done.
