Ask students in your class who show potential in an academic setting. If someone is outgoing or makes jokes, then he might enjoy the drama club.
Stress the fame aspect in posters and flyers around school. Many kids dream of being the next Johnny Depp or Halle Berry. Now they can get a start.
Host an open meeting where you serve pizza and encourage people to come with no strings attached.
Recruit talented people from other activities. For example, someone in the school choir might be interested in singing in the chorus of a musical production. Or, kids in shop class might want to build a set for a play.
Speak at a meeting or parents' night to explain the merits of the drama club. Tell them how studies have shown that doing extracurricular activities help students. For example, the United States Department of Education found that students who don't participate in extracurricular activities are 49 percent more likely to use drugs and 37 percent more likely to become teen parents than those who spend up to four hours a week in extracurricular activities. Afterward, parents might try to convince their kids to join.
Have a guest speaker talk to the school. People such as a director of the local community playhouse or a former student who acted would be good choices. Then, plug the drama club after the talk. It could spark someone's interested in joining.
