Jackie Trailer: Is Natalie Portman headed towards Oscar glory?

Portman takes on former First Lady Jacqueline Onassis, wife to John F. Kennedy, in the Pablo Larrain-directed film

Natalie Portman better start making room on the mantlepiece next to her 2011 Academy Award for Black Swan, it might soon have a roommate.

Her performance as former First Lady Jaqueline Onassis, wife to John F. Kennedy, is already getting rave reviews and some serious Oscar buzz; with the newly released trailer for Jackie leaving a bold, memorable impression.

Considering our already intimate familiarity with Onassis' story, the trailer dispenses with the usual plot points and instead delivers eerie atmosphere by the bucketload; cutting between her joy - dancing with her husband at a gala - to her sorrow, with glimpses of the moments after JK's assassination on 22 November, 1963 and Onassis' washing his blood off in the shower.

It's a haunting piece of marketing rarely delivered with such confidence; focusing on Portman's experience alone as Onassis, as a musical number from "Camelot" plays over the scenes, well-known as including some of JFK's favourite lines - "Don't let it be forgot, that once there was a spot/ for one brief shining moment that was known as Camelot".

Indeed, Pablo Larrain's film is already shaping up to be a must-see for the year, with Portman starring alongside the likes of Peter Sarsgaard, Greta Gerwig, John Hurt, and Billy Crudup.

Jackie hits US cinemas 2 December; no UK release date has been announced.
