Ralph Fiennes felt a lot of pressure making 'Coriolanus'.
The 49-year-old actor makes his directorial debut with the Shakespearean adaptation and admits it was hard to juggle helming the project with also acting in it.
And then, the pressure on the head - Got to move on! And even if you think, 'f**k, f**k, f**k' you can't afford to show it.
He said: "There were days when I thought, 'I haven't got the right performance that I should be giving, but I haven't got time, and I have to move on.'
"And then, the pressure on the head - Got to move on! And even if you think, 'f**k, f**k, f**k' you can't afford to show it."
Ralph admits there were several occasions where he was disappointed with the footage shot each day and was pleased to learn a lot about the editing process.
He added: "Then later, you look at the rushes and you think that's all s**t. And then, thankfully, you learn the magic of editing."
Ralph is rumoured to be taking over from Dame Judi Dench as M in the next instalment of the James Bond series, 'Skyfall', but refused to confirm the speculation.
He said only: "My answer to that is, all this speculation, it's classified information."
