This is very interesting, apparently Nic was going to produce and star in a movie about this man. The article is a remembrance of him, but most of the part about Nic I have put here. Some language may be offensive to sensitive ears.

Anyone who had ever met Slim knew he could talk the nuts off a motorcycle. When he set his mind to something, he really couldn't shut up. I had been working with producer Norm Golightly, Nicolas Cage's former partner at Saturn Films, to develop a film that Academy Award winner Milos Foreman would direct, Cage would star in, and Saturn Films would produce.

On May 22, 2003, Slim and I arrived at Cage's house in Bel-Air. The butler seated us in the living room and offered us a beverage. Slim ordered his usual. "Cuppa coffee in a dirty cup." By this time, I had heard that line a million times, but Golightly seemed to get a kick out of it, especially when the coffee was served in china with a glossier shine than Slim's snakeskin boots.

Cage, sporting a cowboy hat, joined us a few minutes later. WSOP media director Nolan Dalla had asked me to offer Cage a complimentary seat in the WSOP main event. I passed along the invite and told Cage that Edward Norton and Matt Damon played in 1998 to promote the film Rounders.

"Matt Damon!" Slim interrupted. "That boy's lighter than a June frost!"

Right on cue, in that great Nic Cage voice, Cage said, "He only went to Haaaarvard."

Slim and Cage were a perfect match. Slim never stopped talking, and Cage, the observant actor, never interrupted. After about an hour of telling stories, Slim was ready to get down to business. He not only wasn't intimidated by a $20 million-a-picture movie star, he seemed to revel in shaking Cage down. When Slim was in a room, he had to be the alpha male.

Since Cage was not only set to star in the movie but also produce with Golightly, Slim seized the advantage. Mind you, films can take more than a decade to get made and we had only been in talks for a couple months. That didn't stop Slim from imposing his will on the situation. He looked Cage dead in the eye and said, "Well if you're a producer, what the f*** are we waiting for?" The tension built. Without as much as even looking at Golightly, Slim said, "And that Do-Lightly, or Do-Little, or whatever the f*** his name is."

Again, right on cue with that fabulous voice, Cage said, "He actually prefers Do-Hickey."

Even at age 74, Slim always had the most energy in the room and could outlast anyone. I had been in several meetings in which all the other parties felt so drained just listening that they could hardly keep their eyes open. Like a parasite, Slim sucked the energy right out of people. Just as taking their pride or money was what gave him life, he could energetically rob people of their life force, drinking it in through his lungs. After about 90 minutes with the duo from Saturn, I was ready to end the meeting. We had brought a copy of the memoir, so I handed Slim a pen and asked him to sign it for Cage.

Slim grabbed the pen, looked Nicolas Cage dead in the eye, and said, "How do you spell 'prick'?"

Cage loved it. And there Slim was, still as sharp as ever, about to be the biggest of all winners in the poker boom. Phil Gordon was the host of Celebrity Poker Showdown and his book sales far exceeded Slim's. Doyle Brunson, Daniel Negreanu, Gus Hansen, Phil Ivey, and Phil Hellmuth Jr. were making fortunes on and off the felt. But none of them were considered larger than life and were being courted for a major motion picture.Slim was on top of the world.
