Johnny Depp is wrestling with a monster. No, it's not one of the numerous sea monsters from "Pirates of the Caribbean" — it's the franchise itself.

As the world lines up to see the latest installment of the blockbuster series, "Pirates of the Caribbean: On Stranger Tides," Disney has alluded to the fact that this is not the finale of a four-film narrative but the beginning of a second trilogy.

"It's kind of a big monster I got myself caught up in," Depp tells The Japan Times. "I am impressed as hell on the one hand. I'm also, in my mind, keeping it at arm's length ... I don't want it to swallow me up."
