The dark and murky world of online gambling comes alive in new film Runner Runner, a thriller exploring the depths of greed starring Justin Timberlake and Ben Affleck.

Writers David Levien and Brian Koppelman, who penned the 1998 gambling drama Rounders, return to the poker world with Runner Runner, released in US theatres this weekend. While gambling is a core theme, the writers said they were inspired by the behaviours and motivations of shady operators from many other industries as well.

“We never set out to intentionally hit a topic. We loved the idea of a maverick businessman who is immune to extradition.

“It was informed by gaming as well as other business figures,” said Levien of the 20th Century Fox film.

Runner Runner, which owes its name to poker slang, follows Timberlake as a graduate student who goes to Costa Rica to confront an online gambling tycoon played by Affleck, who swindles him.

The world of gambling intrigued the writers for its hypocrisy and how gamblers justify their behaviour

While gambling is actually rarely seen in the thriller, which features luxurious locations, lavish parties and plenty of fight scenes, the portrayal of gambling’s underside was enough to spook casino industry groups like the American Gaming Association (AGA) as they push for a legitimate online poker market.

The AGA has launched a marketing campaign to portray Runner Runner as a “cautionary tale” about what could go wrong in the seedy world of unregulated online gaming.

Both Levien and Koppelman were surprised by the trade group’s reaction. “We find it amusing,” said Koppelman.

Despite their insistence that Runner Runner is not strictly a movie about gambling. Levien and Koppelman appear to be earning reputations as Hollywood’s go-to writers on the subject with credits including the Matt Damon drama Rounders, TV poker series Tilt and 2007’s casino heist movie Ocean’s 13.

Koppelman said the world of gambling intrigued both him and Levien for its “hypocrisy” and how gamblers justify their behaviour.

“These people take giant risks with wild swings of fortune. It’s a rich world to dive into,” he said.

Koppelman added that he and Levien hope to one day write a sequel to Rounders, the critically acclaimed behind-the-scenes look at New York underground poker.

So far, Runner Runner has drawn mixed critical reviews. The film has earned just a 23 per cent rating on review aggregator RottenTomatoes.com and scored 37 out of 100 on Metacritic.com, which rounds up film critic reviews.

Hollywood Reporter film critic Todd McCarthy said the film was a “vaguely ambitious but tawdry melodrama,” adding that it was “lacking both style and insight into the netherworld it seeks to reveal”.

Variety’s senior feature writer Andrew Barker said: “Runner Runner adds up to little more than a charmless, paint-by-numbers thriller.”
