Joel Kinnaman Easy Money

"We have this thing where if you're in jail and you're well-behaved, you get to come out for the weekend and start to get acclimated back into society," Kinnaman said. "But the problem is, things do not go smoothly for JW, who still has all these business plans. And the fact that he's been in prison is a huge embarrassment to the people he wants to impress."

Kinnaman, who previously prepped by studying the dialects and body language of different communities and social classes so that JW could change depending on with whom he's dealing, went deeper this time around by visiting a medium-security prison north of Stockholm. His co-star Mrsic, however, didn't need to. Twenty years ago, Mrsic served three-and-a-half years for conspiring to commit aggravated robbery in an infamous Swedish bank heist when he was 21.

Meanwhile, Jorge Salinas (played by Matias Padin Varela) returns to from exile in South America to Stockholm to make another coke deal, but his plans go wrong and he's on the run once again. Mahmoud (played by Fares Fares) -- who also featured in "Safe House") has a new job with the Yugoslavian mafia, but gets in trouble when two prostitutes escape and he has to repay what they were worth to mafia boss Radovan. His price? Find and kill Jorge. This all happens that very same weekend JW is out on leave.

Though the second film departs from the books, the third returns to the plot of the Lapidus novel "Livet Deluxe," although it's not determined yet when production will take place, Kinnaman said. "It all feels like a family reunion to me," he said. "So I hope to know soon."

Kinnaman also hopes to resume his role as Christer Malm in the Millennium trilogy, after his oh-so-brief appearance in David Fincher's "The Girl With the Dragon Tattoo," in which he just established his character's presence at the magazine. But the actor has yet to hear if and when they will start production on the sequels "The Girl Who Played With Fire" and "The Girl Who Kicked The Hornet's Nest." "I've got all these trilogies," Kinnaman laughed, "but 'Easy Money' is the only one that's really mine. I'm just a guest in 'Tattoo,' so I'm not really a part of that in the same way."

In the meantime, even though Espinosa will not be at the helm for any more of the "Easy Money" films, Kinnaman, who reteamed with the director for "Safe House," has plans to work with Espinosa again, calling him "one of my best friends" and "my Marty [Scorsese]" -- and the  famed director has attached his name to the project and is presenting the film to U.S. audiences. "There actually aren't many directors, if any, who I would rather work with than Daniel," the actor said. "He's a great leader, a great friend, an inspiring person, and he has a couple of masterpieces in him." Kinnaman said the two have "some other ideas" in development, but nothing that he can talk about yet. "Hopefully soon," he promised. "It's a bit in the future, but I wouldn't be surprised if our next movie is an American movie."
