In this episode there is a scene where Whitey (Oliver Coppersmith), is playing pool whilst keeping tabs on the Police Chief (Tim Roth). We see him take a shot, but clearly see there are 2 cue balls (white balls) on the table.
Is this just an oversight, a pretty poor one to be honest, or in parts of Canada / North America, is there a type of pool game that requires 2 cue balls?
Apologies for lack of supporting image.
I watched the scene a couple of times, this is not my mistake, 2 white balls are clearly on the table.
Pictures posted in accepted answer below would suggest I did make a mistake!
