One thing is certain about trying to make a career in film, and that is that much of your success will be determined by who you know. Hollywood is in reality a very small world, and the mover and shakers all know one another, and do business together. So for the aspiring film star or film maker, you need to know how to meet the right contacts in Hollywood.
Again, this is really a small town when it comes right down to it, and the chances of meeting others involved in the industry at every turn are very good. The old jokes about all waiters being actors are actually quite appropriate. So the first thing one needs to do in order to meet contacts is to simply start spending time in the city.
Then you need to be prepared, at all times, in case you actually meet someone that can help in your pursuits. Keep portfolios handy at all times, and keep business cards and the like ready no matter where you go. There is no need to be overly aggressive, but being confident when meeting potential contacts is vital. The competition is stiff in this field, and success will go to the bold and the prepared.
