What an actor needs
There are a few basic things that an actor needs to go out and start the audition process. I will leave out the obvious which is training ang classes to maintain their potential and just stick with the basics:
1. Every actor needs a headshot. A headshot is basically a photo of the actor, as the actor, not a character you would like to be. This headshot should be an 8 x10 frame shot of the actor from the shoulders up. Nowadays, a 3/4 shot is accepted in theatre and film which is a shot of the actor from the torso up or covers 3/4 of the body. The shot should be black and white, but we are seeing more color shots lately. But, a 8x10 headshot is the basic standard. Check the link I have on headshots for more.
2. Every actor needs a resume. A resume is like that of any resume it just lists all of the skills, experience and training that you may have as a performer. The resume should fit only one page and should be attached to the back of your headshot. This connects the name with the face. Click on the headshot/ resume link for more.
3. Every actor needs material. Every audition requires something different, but it is always important to have material that can be ready to present at anytime. A monologue from a play (usually a comic piece and a dramatic piece) should be handy for an actor. Other materials would be a song(s) (if auditioning for musicals) in the correct key and possibly another for variety.
4. If you are pursuing film/ TV it is also important for an actor to have a DVD or VHS recording of your work or a monologue or presentation that markets your talent. Sometimes called "copy" it is a way that actors can email or mail an audition to calls that may be out of town or does not have time to hold scheduled live auditions.
5. Every actor also needs a constant stream of information on the business for auditions, calls and marketing. As an actor you are the product, so you must know how and be able to market yourself. You need to know what you are "castable" for, your type and what not to waste your time auditioning for. You can join several calls on the internet and groups that will update you on the things going on in your area. I will try to list those in the actor resources section
6. Not as important, but needed, when you find yourself getting busy is to reach out and find an agent. Agents are amazing and can get you in many doors that you otherwise could not get into to audition. However, until you find yourself getting steady work or landing big jobs don't seek out agents. Agents help those actors that are helping themselves. Meaning actors that are still marketing themselves. The agent also gets a percentage, usually 20% could be less, but is required to go to the agency when you get paid for work. So do not seek out an agenct ASAP. Start finding work yourself and then you will know when it is time to find an agent.
This is to get you started. Some actors create mailing and e-mail lists. Some actors create websites and various other ways to keep themselves out there showcasing their talents. Check the other links for more details.
