Two mistakes (warning, spoilers inside)
When it's Joanne's turn to bet, Kevin McCarthy(?) says that everyone's got $3500 in that pot except her and that she's got to come up with $500(?) or drop out. At this point Jason Robards(?) says that the pot is gonna get bigger and bigger because all the other players with good hands are going to raise. If everyone else has $3500 in the pot, then Joanne only needs to call the bet and the betting is over, period.
Paul Ford (the banker) says that they did nothing dishonest. It was just good ol' fashioned poker bluffing. Huh? The deck must have been rigged for all five of the other players to get whopper hands.
