Trading Places (1983)
In Trading Places, Denholm Elliott’s Coleman seems like an ideal English butler. He efficiently tends to the household needs of his master, preppy young commodities trader Louis Winthorpe (Dan Aykroyd), who makes a grand gesture of letting Coleman eat his own meticulously prepared leftovers. But Coleman’s actual employers are the Duke brothers (Ralph Bellamy and Don Ameche), whose heartless nature-vs.-nurture experiment involves stripping Winthorpe of all his privileges and bestowing them upon street hustler Billy Ray Valentine (Eddie Murphy) while forcing Winthorpe to live on the street. Coleman’s pretense that he doesn’t recogznize Louis seems like the cruelest of betrayals.
Remarkably, Winthorpe forgives him once Billy Ray discovers the Dukes’ wager and rescues Louis from squalor. In fact, Louis rewards Coleman by including him in his revenge scheme to swindle the Dukes out of their wealth. Of course, that means Coleman has to do a ridiculous impersonation of an Irish priest, but the plan works, and soon, Coleman is rich enough to have a butler of his own.
