The trailer for Jackie is finally out. It looks like this movie is a reminder that Jackie Kennedy Onassis life was far from a fairytale. The film is not to remember how Jackie dressed or what well manners she had. This film is dark. It's a reality check. It's about beauty, bravery, trauma and a roller coaster of emotions.

"People like to believe in fairytales," says Portman as Kennedy Onassis in voice-over as servicemen fold an American flag over her husband's coffin. "Don't let it be forgot that for one brief, shiny moment there was a Camelot."

Chilean director Pablo Larrain's first English-language film has already screened at film festivals in both Venice and Toronto. No, it is not a celebration of Kennedy Onassis as an American icon, it is a story of a widow of the victim of one of the most sensational assassinations of all time.
