I watched Smithereens yesterday. It's interesting in the ways that the story of Wren, the protagonist in Susan Speidelman's film, paralleled the life story that Madonna had been actually living very recently at the time. I'd like to think that Wren ends up rich and famous and with a fake British accent, too.
As for this movie, it's better than an average Behind the Music episode and lead actress Jamie Auld does a terrific job as young Madonna. Worth your time if you're interested at all in Madonna's early years.
