It has been 4 years since I've worked with central casting do I have to completely go through new members orientation again

I started in September 2018 and what they told in the orientation was that a person wanting to come back, needs to update his or her profile. They did not say anything about taking the orientation again. I believe is because they will give information that you already know

They do have introduced new forms you need to fill out since 4 years ago. and since it been that long, you really should update your photo.

Go to the website calendar and look for the updates/reregistration times. They take place Tuesdays and Thursdays
