If you're asking the host of a late-night chat show if he wants to fight you, you know your interview is off to a rocky start.
That's what happens when The Late Show's Stephen Colbert interviews Casey Affleck about his new film, Triple 9.
The interview starts badly, with Affleck taking offence when Colbert gently jokes about his scruffy appearance, something he calls "playful ribbing".
But things quickly take a turn for the worse when Affleck declines to drink his glass of water.
"You really look like a street corner Jesus," quips Colbert, as Afflect cringes.
At one point, Affleck asks: "You want to fight me?"
"It feels like where this is going," replies Colbert.
