Ethan Hawke writes all of his lines by hand.

The 55-year-old film star is always meticulous in his preparation for a role, with Ethan explaining that it helps him to be "extremely critical of the writer, in a positive way".

The Hollywood star told Variety: "I hand-write everything like it's my journal.

"I'm not memorising from a typewritten page; I don't want irrelevant stage directions to be part of it. I try to write it from memory, and then I look and see what I got wrong.

"It also helps me be extremely critical of the writer, in a positive way. 'It doesn't seem like I would use that word four times. I think this is a better word.' Then I record it, and I listen, and I see what I got wrong.

"Take Billie Eilish's Birds of a Feather. I know all the lyrics to that song. I don't know how I know all the lyrics to that song. I absorbed it at coffee shops and on the car radio, and it's in me now."

Ethan is convinced that his approach makes a lot of logical sense.

The movie star said: "If you have a really big speech -- Jon Voight taught me this -- you unlace your shoe. And you have to do the speech lacing your shoe. If I was talking, lacing my shoe, it would be no problem. If I'm trying to remember, then it's difficult to do."

Meanwhile, Ethan previously claimed that "greed" runs the movie business.

The actor acknowledges that the movie industry is "designed to make money" - but Ethan admires actors and actresses who are willing to take financial risks.

Speaking to The Hollywood Reporter, Ethan explained: "Greed runs our universe.

"If you say you just want to make money, everybody understands what you are going for, and they are fine with it. 'Great, yeah, good. Oh, yeah, he sold ten billion Big Macs. Good for him.' No, you just poisoned the whole world."
