Bryan Cranston doesn't worry about ratings or box office success.

The 'Breaking Bad' star holds his own work to a "high standard" so is only interested in taking on projects that bring him personal satisfaction, rather than what will be a hit critically and commercially.

He Said: "I can only be true to myself, so my measure of success is entirely personal."

The 62-year-old actor voices Chief in Wes Anderson's new animation 'Isle of Dogs' and he jumped at the chance to work on the movie, even though he didn't know at the time he wouldn't appear on screen.

But Bryan insists the news didn't come as a disappointment.
