Find a background, or extra, agent in your community. Videos are shot throughout the world, though the top performers generally have established directors, who are found in the top areas of the movie industry, including Los Angeles, New York and Vancouver, British Columbia. An extra agent in one of these locations would be more likely to submit someone for a Missy Elliot music video.
Go to the extra agent and ask if the agency is adding to its roster. If so, the agent will take a photo of you and ask if you have any special skills.
Write down "dancing" as a special skill if you can dance. While it's not necessary, you are more likely to secure a spot in a Missy Elliot music video if you can dance.
Wait for your agent's call for a Missy Elliot video. In the meantime, your agent may submit you to be a background performer in other music videos or in a movie, TV show or commercial.
Make yourself available for background work as much as possible. You will be called more often if you are available all the time. Most agents have an online calendar that you can update with your availability. If you aren't available for a specific day, there is a chance Missy Elliot could be filming a video on that day and you won't even know about it.
