"Finally, and probably most importantly, constantly network with other pros and your peers. In your case, since you desire to work specifically on a feature film, let people know that you are ready, willing, and able to work on that kind of project. Keep networking toward your goal. Depending on your experience and skill set you might need to be prepared to accept a more entry level position, but getting your foot in the door is a big and important first step. Most jobs in feature films, even the less prestigious positions, like Production Assistants received a lot of resumes for very few spots." -- Mikael M.
