After years of false starts and delays, Pirates of the Caribbean: Dead Men Tell No Tales finally began filming in Australia yesterday. And that’s not a moment too soon for the franchise’s star, Johnny Depp, who hasn’t headlined a hit since 2011’s Pirates of the Caribbean: On Stranger Tides. So, this brings up two important questions. First, will a fifth Captain Jack Sparrow adventure resuscitate Depp in a post-Mortdecai world? Secondly, can new directors Espen Sandberg and Joachim Rønning inject new life into a series that ran out of steam two movies ago?
