Pirates of the Caribbean: On Stranger Tides

Skuttlebutt around the interweb is that Johnny Depp may be questioning his involvement in the fourth Pirates of the Caribbean film!

From IGN:

A "regular tipster" for Latino Review claims that "even if (Depp) makes the fourth film, he definitely won't be back for a fifth or sixth. Given that the Pirates franchise was the only live-action property making any money for the studio, they could reach deep in their pockets and keep Depp on for #4, but they're also preparing to replace Captain Jack with a entirely new character if he refuses a fifth and sixth film." If true, might it be the oft-rumored Russell Brand as Captain Jack's brother Jonathan?

Gasp! With the movie still years out and the questionable veracity of internet rumors in general, only time will tell...
