The Coca-Cola Kid (1985) review

Becker (Eric Roberts, who is terrible), a "troubleshooter" for The Coca-Cola Company, travels from Atlanta, Georgia to Sydney, Australia to help improve sales of the soft drink and learns that in the (fictitious) town of Anderson Valley, a man named T. George McDowell (Bill Kerr) is making his own soda using real fruit flavors - while this is happening, office assistant (and single mother) Terri (Greta Scacchi) is actively trying to seduce Becker.  At this point in his career, Makavejev was already known for his radical and thought-provoking films and although this does have a political component to it - as a look at how mega-corporations wipe out small businesses and "pander" to different cultures (Becker demands the ads have an "Australian sound") - it's so innocuous even the folks at Coke allowed them to use the name (and they are a litigious bunch).  The love scene on a bed of feathers with Roberts and Scacchi may have been a miserable experience for her (Roberts allegedly did not behave like a gentleman) but it is a pleasantly erotic (if unexpected) moment.
