Ford Wants Whip or no Indiana Jones
There is a fear that Harrison Ford will walk and not make a fourth Indiana Jones movie as he has been told that he cannot use a real whip [...] he has been told by the studio that is against new health and safety laws to allow him to use a real one so instead a computer generated has to be added in later

És que és un perill fer servir un fuet real a la pel·lícula, imagina't que algú pren mal.
