Towards the end of Martin Scorsese’s Goodfellas (1990), mobster-turned-informant Henry Hill is confronted with the following statement from a contemptuous defence attorney in court: “People call them rats because a rat will do anything to survive. Isn’t that right, Mr Hill?” In Scorsese’s film, the viewer follows Hill across several decades of involvement with an Italian-American crime syndicate, up to the point that various complications of his Mafia career collide in a disastrous fashion. Convinced that he and his family are marked for certain death, Hill eventually decides to become an informant for the FBI, testifying against his former friends and then entering the federal Witness Protection Program.
“Rats” and informant characters are not uncommon in crime movies, though in cases where they may be the protagonist you will often find them serving the part of a double agent or mole. They may be an undercover FBI employee infiltrating the mob, such as in Mike Newell’s Donnie Brasco (1997). In Andrew Lau and Alan Mak’s Hong Kong thriller Infernal Affairs (2002), and Scorsese’s subsequent American remake The Departed (2006), you even have informants on both sides of the law: an undercover cop, deep in the criminal underworld, trying to smoke out a mob mole lurking in the police department.
In mob movies where the lead eventually turns informant after some pressure, this will traditionally happen in the third act after a few hours of transgressive highs of the lifestyle leading to destructive lows. A rarer commodity is a film mostly set after the mobster’s choice has been made to spill the beans. After all, the derogatory term “rat” is used to denote that such a person is the lowest of the low in an environment that may posit the notion of honour among thieves. The perceived wisdom may be that audiences won’t want to follow such a character for a whole film; one that would, by its very nature, skimp on some of the glamour and success Mafia tales usually show before things go terribly wrong. But that is exactly what revered Italian filmmaker Marco Bellocchio has made with his subversive spin on the mob movie, The Traitor, in which the title character heads down the informant path within the opening half-hour…
