Los Angeles — Flying through the clouds with a black parrot umbrella and holding her signature carpet bag, whimsical British nanny Mary Poppins made her "practically perfect" movie comeback on Thursday, more than 50 years after first charming audiences worldwide. "Mary Poppins Returns," set some 20 years after the film that made Julie Andrews a star, had its world premiere in Los Angeles, featuring a new cast and new music but with a nostalgic nod to the original. — Reuters
