Dude why go to Hollywood when we have YouTube. That's where all the stars are discovered these days. All you need is a digital camera and a computer. Get some friends in, make up a few dodgy sets in the Garage and away you go! Now it may not quite be Hollywood but it could pass for Collingwood!
After all isn't this all they do for Home and away?
In all seriousness TTID, Unless you can look and act like Brad Pitt straight off the bat or have a top line agent in the US already, you will struggle. I'd suggest you try and get into NIDA as a first step as it has an excellent reputation both here and overseas. Score a decent agent and see what they can get for you. I'd try and focus on local films and TV first. Well that is if you want longevity in the industry. Otherwise you might end up being typecast as zombie #3 in horror films for the rest of your life which is like playing Full Forward for Collingwood in the Alan Didak Show.
Now if you believe you have a serious X Factor that will separate you from the thousands of other hopefuls who venture to Hollywood in the hope of a break then props to you and good luck, but personally I'd test the waters here first. I know I bagged home and away but hell even Russell Crowe did Neighbours!!
