A group of community leaders in Beverly Hills are trying to raise $30 million to build the state’s first full-time professional children’s theatre. “The move comes at a critical time for arts education as budgets shrink for public-school programs and computers and television claim a substantial share of kids’ leisure time. At the same time, children’s theater, traditionally the stepchild of the professional stage, is maturing to new levels of excellence as evidenced by last month’s Tony nod to the wunderkind of the genre, the Minneapolis-based Children’s Theatre Company, the first such troupe to win the award.”
