The contacts you made with them while film students might lead to some great jobs in the future. Internships are always a good idea, but they aren't as readily available in Montana as they are in major production areas. However, internships with professors, local TV stations, or local production companies can certainly lead to a career in the industry. Working for school credit will provide you with the kind of information that is not available in the classroom. If you are a student, challenge yourself to produce quality work, which you can enter in film festivals.
Persistence is essential.
You want to get on a film, get to know the people in the production office. Charm is also essential, but do not continually annoy the production office with you requests for a job. This will ensure that once you have a job, you'll keep the people that hired you happy. Get your hands on every bit of information about the industry that you can, so when you do get your first break, you'll know the lingo and it will seem as though you've already worked in production before. Contact the Film Office to ask about getting on the Montana Crew list.
