Eddie Murphy understood the Commodity’s Market as explained by the Duke Brothers.
I like the part where they explain pork bellies, which are used for bacon, which you would find in a bacon, lettuce, and tomato sandwich. The look Eddie gives the camera is classic.
I remember seeing on of those "the making of" shows on Trading Places. Dan Ackroyd and Eddie Murphy were asked about trading and both said they had now idea how the commodities tradng works.
