Once there was a boy who dreamed a star could be his new friend — if only he could catch one. He tried climbing to the top of the tallest tree. He tried flying in a paper rocket ship. Nothing worked. Just when the boy was about to give up, he discovered something as dazzling and special as the star he was seeking Featuring colorful projections and choreographed movement, “How to Catch a Star” is a whimsical tale of discovery, friendship and delightful surprises. For ages 3, up. $20. On stage at the Kennedy Center, until Dec. 16.
