Everyone already knows about “The Beguiled,” which premiered to acclaim at Cannes and opens in select theaters June 23 via Focus Features, but her upcoming performance film “La Traviata” is flying a bit more under the radar. Hopefully that changes with the release of the official trailer below. Featuring costumes by none other than Valentino, this adaptation of “La Traviata” finds Coppola bringing the recent stage revival of Giuseppe Verdi’s classic opera to the big screen. It looks sumptuous and elegant and everything you could want from a night out at the opera (without actually physically being at the opera).
