Question: What Australian actor/filmmaker played a former FBI agent convicted of murder charges stemming from his relationship with the Winter Hill Gang?
Context: Richard Joseph Schneiderhan (c. 1934 – September 16, 2015) was a former Massachusetts State Police Lieutenant in the Attorney General's Organized Crime Unit.  He was convicted of conspiracy and obstruction of justice stemming from his relationship with gangster Stephen Flemmi and the Winter Hill Gang.  Schneiderhan had warned an associate of fugitive mob boss James "Whitey" Bulger that Bulger's brothers' phones were being monitored by the FBI. Stephen Joseph "The Rifleman" Flemmi (born June 9, 1934) is an American gangster and close associate of Winter Hill Gang boss Whitey Bulger.  Beginning in 1975, Flemmi was a top echelon informant for the Federal Bureau of Investigation (FBI).  Despite delivering a great deal of intelligence about the inner workings of the Patriarca crime family, Flemmi's own criminal activities proved a public relations nightmare for the FBI.  For this reason, he was prosecuted under the Racketeer Influenced and Corrupt Organizations Act (RICO) and sentenced to a long term of incarceration. Timothy A. Connolly 3rd (born May 27, 1958), aka "Timmy Connolly" and "TC", is a former South Boston bar owner and mortgage broker, who wore a wire inside the infamous Winter Hill Gang and helped the federal government indict their two leaders, James "Whitey" Bulger and Stephen Flemmi ("The Rifleman").  The public was led to believe that Tim Connolly was merely a businessman and an innocent victim of one of Jim Bulger's many extortions.  But in truth, Tim Connolly was secretly a "made member" of the Winter Hill gang and a high ranking lieutenant in this Bulger crime family. John C. "Jack" Ryan (born 19 June 1938) is a former FBI agent and police officer.  He had been an FBI agent between 1966 and 1987 before being fired for refusing to investigate nonviolent activists.  He lost his job in September 1987 ten months short of retirement.  He was thus ineligible for a full pension and had to live in a homeless shelter.  In a report by the "LA Times", he stated his belief that the Bureau could reinstate him to a position which would not conflict with his personal beliefs that U.S. involvement in Central America is "violent, illegal and immoral." John Joseph Connolly Jr. (born August 1, 1940) is a former FBI agent who was convicted of racketeering, obstruction of justice and murder charges stemming from his relationship with James "Whitey" Bulger, Steve Flemmi, and the Winter Hill Gang. Kevin Weeks (born March 21, 1956) is an American former mobster and a longtime friend and confidant to Whitey Bulger, the infamous boss of the Winter Hill Gang, a crime family based out of the Winter Hill neighborhood in Somerville, Massachusetts. Edward "Punchy" McLaughlin (died October 20, 1965) was a former boxer and a member of the "The McLaughlin Brothers" gang of Charlestown, Massachusetts.  Vincent Teresa, former mobster described Edward in his biography "My Life in the Mafia" as, "Punchy was just as crazy as George... a legbreaker for the longshoreman's union.  Punchy was a cuckoo and as hotheaded as they came.  After his brother Bernard McLaughlin was murdered in October 1961 by their former friend, "Winter Hill Gang" leader James "Buddy" McLean (Punchy and his brothers had been known to perform hits for gangs all over New England, including the Winter Hill Gang), Punchy and brother George McLaughlin murdered Russell Nicholson who was rumored to be McLean's driver in the shooting.  After surviving many assassination attempts, one where he lost a hand and another where he lost half his jaw, Punchy was on his way to Boston's Suffolk Superior Courthouse for his brother Georgie's murder trial, and was shot dead at the Spring Street Metropolitan Transit Authority Loop in West Roxbury, Massachusetts. John "Red" Shea (born August 12, 1965) is an Irish-American former mobster from Boston involved in narcotics and an associate of crime kingpin Whitey Bulger and the Winter Hill Gang during the 1980s and 1990s.  He was indicted on cocaine trafficking charges in 1990 and served 12 years in prison. Louis Eppolito and Stephen Caracappa are two former New York Police Department (NYPD) police detectives who worked on behalf of the New York Mafia, principally the Lucchese crime family, while they committed various illegal activities.  In 2006, they were convicted of labor racketeering, extortion, narcotics, illegal gambling, obstruction of justice, eight counts of murder and conspiracy to commit murder, charges stemming from the 1980s and the early 1990s in New York City, and in the 2000s in Las Vegas.  Both were sentenced to life in federal prison. Joel Edgerton (born 23 June 1974) is an Australian actor and filmmaker.
