"When you watch a cut scene in Uncharted 2, it feels like the actors are playing off of each other, and it feels like there’s a real relationship there, and that’s because there is." "They were together in the pre-shoot, playing with dialogue, tweaking lines - and then when it came time to record actual dialogue for the game, they were in the same room, playing off of each other, shooting the scene just as if it were for a film." What I found meaning of 'play off' is 'make joke' or 'deceive'... but I think in this context, these meaning looks weird. Do you know what he wants to say? Thanks in advance.
