Seek a nearby community or local theatre
You need to look for any local or community theatre. In case you do not know any in your neighbourhood, you can always take help from Google Maps. Type theatre in it and zoom in at your location. Now you will be able to see many theatres in your area. If you still cannot see any theatre, you can type your town and theatre e.g. jolt down Smallville theatre in the search area. You can even watch out for any colleges in your area and see their theatre programmes.
After finding a nearby theatre, you need to participate in it. Note down the theatres’ web address and apply in it. Also save their phone number and get information by directly calling them. In case you are opting to act in a college, you need to take special permissions from principal or other officials. Ask them whether they permit non-student actors and check their requirements.
Make resume, head shot and cover letter (if required)
You need to make resume, head shot and a cover letter of yourself. Many theatres won’t require this but in case they ask, you need to come prepared. You should jolt down any of your past skills, your school’s ply participation and any other work you have done.
Audition for the role
Next you need to audition for the roles available. In case there are no roles available, you need to be patient and wait for the call. Something might come up or someone has to go in the last minute, you will get his part. However, in this scenario you should have good acting skills. You need to speak clearly, understand the stage and be confident when auditioning.
