Why would you upload your reel to Actors Access and other sites? Real acting jobs are only available through reputable agents. Those sites are scams or only get you student films and the likes. You would know that if you had any real experience, quality training, and an agent to begin with, and you would've used your reel for real auditions, which you would've gone to, and to get an agent, instead of uploading them to those sites. Not to mention that since you don't know that stuff, you can't possibly be in the position of being in a national commercial to begin with.
What you're saying doesn't add up at all. So either you're lying or not saying the entire truth (for example you were an extra, and in that case it's not considered an acting gig and therefore you don't put that in your reel or resume).
Considering that, you will not get the footage. You usually don't, anyway, so why would you.
@Annie, thanks for exposing that you don't have an agent, don't have experience, don't have the training... nothing. Because that's not true AT ALL. Agents don't connect their clients through websites. When there's casting for specific roles for a specific production, casting directors approach agents they know personally and trust with a character background. Then the agents go over their list of clients and submit only the ones that may fit the role(s). Out of those, the casting director invites to audition only those who don't only may fit the role but also those who have the most experience and training. No one serious uses those websites. Professional productions spend a lot of money, and they need to know they hire only highly-experienced and highly-trained PROFESSIONALS. They're not looking for amateurs or beginners. That's why they use agents. Agents filter through, that way saving everybody's time, money, and effort - like going on a website in the hopes of finding someone out 99.9% amateurs. Which, by the way, only amateurs sign up for. Real professional actors don't need those websites for real auditions. And the only "agents" who use those websites are scammers who only want your money. Which, by the way, you're never supposed to pay upfront. But, yeah, you don't know that either apparently.
You're lying because you have no idea how it works in the first place. How it REALLY works is one of the things you learn in a quality acting school, where you never went obviously. And since you don't know how it works because you never went to a quality acting school and had enough experience, you can't land an agent. And if you can't land an agent, you can't go to those auditions and land roles in the first place. Got it?
Why would you ask that? Because it's either not a national commercial but something local at best, or you were an extra (definitely not a lead), or you were scammed. Or maybe you're just bored. It doesn't add up. And once again, if you knew how it worked you would know that. Actually, you didn't have to ask this question in the first place.
Don't try the "no, YOU don't know how it works." I know the truth, and you're making a fool out of yourself. Another reason to believe you're lying about that commercial, you're a liar. I'm not trying to be mean, but you need a serious reality check.
One thing I agree on though. You are an innocent kid. Which also says the chances you do have the experience and training are so much lower, and the chances that you got scammed or are under the wrong impression are much higher.
That said, if you gave more details it would be easier to help you. FULL details. Like how you got to this production in the first place, what were you told, how much you paid and got paid, where you're located, etc. This might shed some light. But understand that there's a very good chance that wasn't what you thought it was. And that you're not supposed to get the footage at all.
