Once again, Dave is needed in another movie set because the actor can't do it since he might get hurt. For Dave, this is a great opportunity not only to earn, but prove to the directors that he is an asset in the industry. Dave dreams of becoming a big star one day.
The idea here is to get a perfect landing. Well, that is what you would want to do, but there are nothing wrong with a bad landing since you will still earn. However, you will earn more with a great landing. With the money that you are getting, you can upgrade your car, so that you can perform better next time.
