Weeks, played by Jesse Plemons in the movie, was one of Bulger’s most trusted associates. He spent about five years in prison for assisting Bulger in several murders and was a cooperating witness for the government in Bulger’s trial.

He’s not happy about being portrayed as a “low-life” thug in the movie, and doesn’t think Depp’s version of Bulger is accurate either.

“The only resemblance to Whitey’s character was the hairline,” he told The Daily Beast. “And the mannerisms—the way that Whitey talked to us—he never swore at us.”

Among the other things Weeks takes issue with is Bulger supposedly being a “doting father,” and the portrayal of the FBI.

“The movie is pure fiction,” Weeks says.
