Leonardo DiCaprio has revealed that he is never satisfied with the acting work that he produces.
He teams up with Martin Scorsese once again for the adaptation of Dennis Lehane's novel Shutter Island.
Despite bagging two best Actor Academy Award nominations in recent years DiCaprio is still looking to achieve the perfect dramatic performance.
Speaking at the UK press conference for Shutter Island the actor said: "[When will I] lighten up in general?! I don't know really, I respond to what I read and what I've read in these roles are characters that have moved me emotionally.
"It's very much a throwback to what moved me in cinema at a very early age, those were the types of characters that I felt emotionally connected to.
"You never really think that you've arrived there or done that role that satisfies that, so I'm driven to be able to some day, in my mind, emulate or get close to the great masterworks of great performers I've seen in cinema from years past.
"I don't know if that thirst will ever be quenched. I would love to try other genres and I look forward to doing them, it just depends on what moves me emotionally."
It's the first time that the pair have worked together since the Oscar success of The Departed back in 2006.
Shutter Island is released 12th March.
