David O Russell has confessed he felt a sense of nostalgia for the 1970s while making his new film American Hustle.
The Silver Linings Playbook director's new drama - starring Bradley Cooper, Jennifer Lawrence, Amy Adams, Christian Bale and Jeremy Renner - is inspired by the FBI Abscam operation of the late 1970s, which David describes to Deadline as a "more innocent time, when things were slower, more analogue".
The Oscar-winner admitted he felt something has been lost in the digital age.
He said: "Money appears out of thin air or even disappears out of thin air. It's not just currency - everything is kind of intangible.
"The internet is intangible. Almost the whole world is intangible.
"I was at Skywalker Ranch yesterday, and one of my favourite things up there is the old-fashioned library. It's a very beautiful room that George Lucas created. If you happen to be looking for an old Life magazine that maybe is about an Iowa town, you might stumble across something that you never would have seen. I think that most stumbling on the internet leads me to a guy riding a bike off his roof who ends up breaking his neck, a video that I can't even believe I'm watching.
"There's a magic in the analogue world that I think is special. The longer it takes to get something, the more you value it. And the shorter it takes to get something the less you value it.
"Anyone who's raised a kid can tell you this. If the kid gets stuff right away, they're not going to respect it."
