I have no experience with Hollywood but heres some general advise on switching industries: 1) Build a portfolio before you look for a job (film shorts starring you with your friends before moving). 2) Engage with the industry as much as possible before moving, read blogs, follow industry folks on twitter, etc. 3) Plan excessively. Pick a few areas you could feasibly live in in LA. Try to line up roommates. Start tracking interviews you would go to now so you know how to find them. Maybe check into who they end up casting so you can get a better sense of what the ads are looking for. Benefits of this approach include: having provable experience, familiarizing yourself with the industry, possibly having a network to tap, at least knowing some people in town. Enjoy LA.
