Hi
It sounds as though you have lots of really great skills and some good experience. It is definitely worth listing your skills (languages, horseriding, dance, singing) on a CV - not sure what runway is, but probably leave that off?- LAMDA bronze you can list if you like but I suspect it won't be of
major interest to an agent - the horseriding skills will also be of interest to an extras agency by the way . It's not so much that an agent wouldn't be interested in
you as a performer(because they might be!) it's that I can't see how you would be able to afford the time and money to get to things like commercial castings - which are a complete lottery and you might attend 30 of them and never get a job... An agent will want to know that you have good availability. All of your great skills (languages etc) will be of interest but they are not unique skills if you see what I mean, so I don't know whether they would be enough to get an agent to take you on if you are a long way from any available work. Even if you look Italian, if those doing the casting are looking for an Italian girl, they will prefer to find a native Italian. Even if you speak other languages fluently, the CDs will prefer native speakers. It's only if they can't find them that these extra skills push you further up the pecking order.
Where do professional productions happen near to you? Is your area often used for filming? If so, it will definitely be worth getting on to the books of an extras agency. It won't make much difference for speaking roles usually - these tend not to be cast on a geographical basis. Where are productions generally cast? Do you know? Can you find out? In the UK, most things are cast in London. Some are cast in Manchester, or Cardiff, or Bristol or Birmingham or Edinburgh etc but the vast majority are cast in London. This is true even when the production itself takes place somewhere else entirely. Where is Ireland's production "capital"? Is it Dublin? How close are you? Where are the subsidiaries - are there any? These are the questions you need to ponder because the reason to get an agent is to get work (obviously
) and you need to think about your ambitions in a very practical way.
In your response, you haven't really addressed the question of your geographical location. Do you not think this is likely to be a problem?
In terms of looking unusual - yes, that can sometimes be a very good thing. If you stand out from the crowd you are likely to be remembered. However,sometimes unusual looks can work against you as there also tends to be work for conventionally "good-looking" people - particularly in commercials.
It's great that you have been approached to do some modelling, but do take care - this is an area where scams often operate. Are you convinced about the bonafide nature of the talent scout? Where were you when you were spotted? Do take care that you are not taken in by a scam and think very carefully and ask lots and lots of questions before parting with any money. Don't sign anything without asking for time to take paperwork away and think about it. Don't part with any money "on the day" (personally, I'd say don't part with any money at all!). Contact the agency direct and ask whether you and your parents can go into their offices for a meeting and discuss the practical problems that would arise for someone living in a rural area. I would suggest that exactly the same things apply for modelling as for acting - and that an modelling agent will have the same reservations as I would expect an acting agent to have: how will you get to auditions/castings? how long will it take you to get there? will your school give you time off? who will chaperone you?
I would regard the modelling and acting as two separate things. Make sure you don't sign anything with the modelling agency that precludes you signing up to an acting agency if acting is what you really want to do. By all means write to the acting agents whose details you find and send them your CV and photo. Check on an agent's website first (if they have one) to see how they prefer to receive submissions. If you can't find this information then I would suggest calling them first: this allows you to check that they are happy to receive details and also allows you to find out the correct name for your covering letter. You might also want to consider trying to get experience in short films/student films so that you can increase your experience and perhaps get a showreel together - this can be very useful when it comes to interesting agents in your work.
Good luck!
.. I never thought my horseriding would really be of interest for an agent? So would surfing, rock climbing, scuba diving, diving and swimming be of interest to them? (I do a lot of activities)
