A directory of actors and actresses is available on IMDb. The site tracks up to date information on all working actors and actresses, with personal info as well as the status of their upcoming projects.
IMDb features the STARmeter, which determines the popularity of actors by how often they're searched. As of Nov. 19, 2015, the most popular star on IMDb is Léa Seydoux, followed by Daniel Craig, both of whom currently appear in "Spectre."
In addition to the STARmeter, IMDb features a general search feature, with which actors and actresses can be searched by name. Additionally, all movies and television shows listed on the site feature full cast lists, allowing users to find an actor based on one of their roles.
