After a string of flop films like `Transcendence` and `The Lone Ranger`, actor Johnny Depp says it is difficult to live up to the success of his "Pirates of the Caribbean` film franchise.

The actor, who portrayed the character of Captain Jack Sparrow, opened up about his career in an interview with Details magazine, reports usmagazine.com.

`It's like being a dog at the track. They expect you to live up to some race you happened to be in and won accidentally. From that first second, you're nothing more than a commodity. They have expectations of another 'Pirates'. It's great if something works. Boy, that's killer. But God, to have that as your design... it's ugly, I think,` the actor said.

The 51-year-old also said that he doesn't care about what the critics have to say about his films.

`First, I reached a point where I cared so much and was so diligent in terms of approaching the work. Then you get to where you care so f--king much that it gets goddamn beleaguering, you know? But then a great thing happens.

"Suddenly you care enough to not give a f--k, because not giving a f--k, that's the total liberation. Being game to try anything," the actor added.
