where to begin . the special effect should be name special defect and when the director shout action i guess he also indicate to the actor to carry out the bad performance they could think of . maybe he be annoy with the producer and want to make sure that they would not recover a single cent out of their investment and that the work would be a case study of how not to make movie . or maybe he hat art school and want to be an accountant but his family do not let him . the only thing that be sure that whoever employ him in the future be because it in love with him ( so it objectivity jump through the window ) or because he change it name and delete all past previous reference .
