The Barbie doll has survived 57 years of changing fashions and mores and by changing with the times. The Barbie of today is pitched to kids (and adult collectors) as a fashionable, confident woman who can be an astronaut, a doctor, an air force pilot or homemaker from almost any cultural background — a far cry from her origins as a strictly white fashion model. She's been attacked for promoting unrealistic ideas about women's bodies and treasured as a gay icon. Director Susan Stern did a deep dive into the controversy and love surrounding the doll and its creator, Ruth Handler, in her 1998 film Barbie Nation: An Unauthorized Tour. The film screens tonight at 7 p.m. at the Missouri History Museum (Lindell Boulevard and DeBaliviere Avenue; www.mohistory.org) as part of the museum's current exhibition on toys. Admission is free.
