Actors must regularly attend auditions to compete for roles in theater productions, films, television shows, commercials, and other projects. This involves preparing audition materials, such as monologues or scenes, and showcasing their acting abilities to casting directors, producers, and other decision-makers. Commercial actors specialize in appearing in advertisements, commercials, and promotional videos to promote products, services, or brands. They are skilled at delivering persuasive performances that capture the attention of viewers and effectively convey the message or selling points of the advertised product or service.
