The 26-year-old British actor plays a billionaire tycoon Eric Packer in the movie and despite the depressing topic, he thinks there is also a positive side to the movie, reported Contactmusic.
"The first time I saw it, I didn't think about the greater scope of the movie, and then I heard people's reactions about things like nihilism and things like that. I think it's actually a really hopeful movie.
"I think in a lot of ways, when I look at the world - maybe I am just a depressive - I think sometimes the world does need to be washed and cleansed, and that's the hope of it", he said.
Pattinson's character has been referred to as "a blood sucking capitalist" but director David Cronenberg says they ignored the baggage of his vampire character Edward Cullen from the "Twilight Saga" series.
"We just didn't deal with it. It is very easy to say that this character is a vampire or a werewolf of Wall Street, but that is fairly superficial. He is a real person and a real character in the movie. An actor cannot play an abstract concept. This is a real person with a history and a past, which is not 'Twilight'. It is 'Cosmopolis'", Cronenberg added.
