While all the bills Leonardo DiCaprio throws around in the "Wolf of Wall Street" are fake, the Secret Service says movie money is being used in real life because it's easy to purchase it online on websites like Amazon and eBay.
"This problem is definitely rated R," New York Sen. Charles Schumer said at a news conference Friday.
The movie money is typically printed with "For Motion Picture Use Only." But because the font is so similar to the look of real currency, at a quick glance, many workers at cash registers just don't spot the fakes.
"You can't tell the difference, you really can't," New York's senior senator said. "Merchants and consumers should be really careful."
According to the Secret Service, there's been a 25 percent surge in the movie money in the counterfeit marketplace. The agency recently launched Operation Quick Glance to encourage retailers to take a closer look at the bills they're taking in this holiday season.
"They may say "replica" or they may say "play money," said Matthew Fishler, a U.S. Secret Service special agent. "These notes are a violation of federal law. They can be arrested."
While it's not illegal to simply possess the movie money, Schumer is encouraging the Internet Association, which represents online retailers like Amazon and eBay, to team up with the Secret Service in hopes of banning the fake currency from being sold to the public at all.
"It shouldn't be Mission Impossible to prevent these fake funds from being passed off as the real thing in the first place," Schumer said.
A spokesman for the Internet Association confirms the group has received Schumer's letter and looks forward to working with him about his concerns.
