The Last of Robin Hood, which premiered at the Toronto International Film Festival last year but hits theaters August 29, chronicles Errol Flynn’s relationship with his teenage chorus-girl lover, Beverly Aadland, just before his death of a heart attack at the age of 50. Kevin Kline and Dakota Fanning play Flynn and Aadland, respectively, with Susan Sarandon as Beverly’s ambitious stage mom who enables the sordid affair. It looks like the three of them are doing most of the heavy lifting — although we do get a glimpse of Mad Men’s Bryan Batt (hi Sal!) — in a trailer that seems to lean pretty heavily on quirky banter, bouncy music, and Old Hollywood glamor, considering that the film’s premise is statutory rape. But hey, aren’t those old-timey outfits great?
