If you want to get a start on your TV career, you're going to have to get going on some TV casting calls. It's no use laying around the house daydreaming about it, and casting calls for TV aren't so scary, in fact, it should be invigorating. Land a role in a new hit TV show and you have it made. As an actor, even if your goal is to eventually work in film, television work can give your career a huge push in that direction, opening up many doors that would have otherwise still been closed to you as you search for only casting calls for the silver screen.
In addition, if your show remains on the air for years, this will give you the chance to save up in order to produce your own film project starring you in a role you create for yourself. A casting call you go on for TV may be only the beginning of a long career in entertainment. You can learn all about production and shooting styles, and hone your acting skills. There are casting calls for TV being held during most of the year, but most are held during pilot season when new shows are being put together to be proposed for the Fall TV schedule.
TV casting calls can be high pressure, but put it all in perspective, grin and bear it. Even if you enter one of these sorts of casting calls, dreams of being a TV star dancing in your head, and the first thing you hear is someone yelling at the top of their lungs about how there hasn't been one marginally talented person who has passed through that day and they're absolutely fed up, don't panic, you now have a new acting job. You must now act like you've been through a zillion casting calls for TV shows of all kinds and no matter what the people at this particular casting call say to you, you will keep on with your plans to become a big TV star one day.
