As a character, Peter Pan is famously impervious to the ravages of age and to changes in the world beyond Neverland. It’s a different matter, however, when it comes to stage depictions of J.M. Barrie’s creation.
Take the clunkily titled “Cathy Rigby Is Peter Pan,’’ which has arrived at the Citi Wang Theatre for a brief run that ends Sunday, in what is billed as Rigby’s final appearance in a role she has been playing on and off for decades. There was a time when this singing, dancing, flying production of Barrie’s 1904 play, directed by Glenn Casale and costarring Brent Barrett as Captain Hook, might have seemed like something special.
