Kevin Bacon thinks his 'Black Mass' role ruined his 'Six Degrees' game

If you're a fan of playing "Six Degrees of Kevin Bacon," you'd better get a few rounds in before Black Mass hits theaters on Sept. 18. After then, as Bacon himself says, that game is pretty much "over."

"There's a lot of people in this movie that have worked with a lot of people, so exponentially, I think it just blew up," he said Tuesday on Today. "It's over."

For the uninitiated, "Six Degrees of Kevin Bacon" is a party game that operates on the principle that everyone on earth is connected through six or fewer other people. Naturally, it's Kevin Bacon-focused, though, and challenges film lovers to connect any actor back to Bacon in the fewest number of steps possible.

And given all the stars in Black Mass — Johnny Depp, Benedict Cumberbatch, Adam Scott, and others — the whole game just got a lot easier. Or, at least in Kevin Bacon's mind it has, since he's more or less connected to all of Hollywood at this point.

For his part in Black Mass, Bacon portrays Charles McGuire, who the Philly native describes as "the voice of reason" for the FBI. He appears alongside star Johnny Depp, who plays gangster Whitey Bulger.

"I play a character who is kind of a combination of a lot of guys who were head of the FBI field office at the time," he told Today. "He's sort of the voice of reason at the time, in terms of the FBI."

Most recently, Bacon celebrated his 27th anniversary with wife Kyra Sedgwick with a snapshot on Instagram.
