In a cover story interview with Entertainment Weekly, Johnny Depp says that even he found the movies a bit confusing.
"I remember talking to [director Gore Verbinski] at certain points during production of 2 or 3, and saying: 'I don't really know what this means.' He said, 'Neither do I, but let's just shoot it.'"
As Vulture puts it, "If those movies eventually made sense in postproduction, Depp admits he wouldn't know it," as Depp says he saw the first one but hasn't gotten around to watching the other two.
Well, now it's time to make it a quadrilogy; the fourth movie, Pirates of the Caribbean: On Stranger Tides, opens May 20.
Will other movies coming out this summer where sequels weren't clearly planned initially make sense in the end? We'll have to go see X-Men: First Class, the Hangover Part II and Transformers 3: Dark of the Moon to find out.
