Brad Henry has just purchased the film studio of a movie company that specializes in action adventures. He found that the company did not try to estimate the cost of making a movie. Instead it just gave the producer a budget and told him$/$her to make a movie within budget. Mr$.$ Henry does not like the former movie$-$budget concept and desires to establish a formal cost estimation system.

Required:

What are some of the potential problems that may be encountered in changing from a budget to a cost estimation movie$-$making system?
