Pirates of the Caribbean On Stranger Tides hasn’t hit theaters yet, but Disney already has plans for a follow up. According to Deadline, the studio has commissioned writer Terry Rossio to pen the yet to be titled sequel Pirates of the Caribbean 5. This news confirms the speculation that we’ve heard over the last few months about Stranger Tides marking the start of a new trilogy.

The site claims that even though Rossio will return for a fifth outing, his writing partner Ted Elliott will not. He’ll handle the screenplay for this sequel solo. Disney is also looking to rope director Rob Marshall into helming the next film, now that his first installment in the franchise is in post production. Johnny Depp is also expected to return for the movie, even though a deal hasn’t been locked in place.

We weren’t sure if a fourth film should have been made, let alone a fifth or even a sixth one. Disney really wants to ride this thing until the wheels fall off. Pirates of the Caribbean On Stranger Tides is expected to open in theaters on May 20, 2011.

What story could they cover next? What should Jack Sparrow’s next adventure be?

Do you think Pirates of the Caribbean 5 is a good idea?
