In the sexually charged new drama Adore, Robin Wright and Naomi Watts play two longtime friends with so much in common: Both are beautiful blondes who live on the Australian shore, each raising a strapping young man of a son. Soon enough, though, the chemistry between Wright and her friend’s son (Xavier Samuel) turns positively sinful — as you’ll see in this exclusive clip, which also features Wright’s fetching Aussie accent — and the ensuing affair prompts Wright’s own son (James Frecheville) to make a retaliatory move on Watts. (To paraphrase the great bard of our time, Janeane Garofalo in The Truth About Cats and Dogs: You can love your best friend’s son, just don’t love your best friend’s son.) Suffice it to say that things get steamy and complicated among this foursome right quick, and you can watch what happens soon when Adore bows on demand and in theaters September 6.
