Analysing an indecent proposal

We were preparing a short study for conflicts and negotiations using a movie scene as an example. Someone suggested Indecent Proposal, so we took the scene were John actually makes the offer (Better watch the movie if you haven’t). When I had watched it for the first time, it was a five minute scene of a horny and arrogant businessman against a needy and faithful couple.
But now, it was more complex. I was watching it as a proper negotiation. The covert agendas of the characters and the actual conflict now seemed entirely different! John’s real motive was to satisfy his ego by driving home his point(money can buy anything). Sleeping with Diana wasn’t important but just a means to his end. In case of David, more than protecting his wife and their relationship, he was trying to protect his own male chauvinist ego.
Another interesting agenda was how they went about the negotiation.John had complete information on the couple ( as detailed as knowing which dress Diana liked) and he didn’t offer them money, but “A million dollars. A lifetime of security, for one night“. The couple, on the other hand, was instinctive, but David was already thinking about it when Diana replied for him “He’d tell you to go to hell“.
Something tells me that I have taken up really interesting courses in my 2nd year.
