Natalie Portman Channels Jacqueline Kennedy in 'Jackie' Trailer

The biopic hits select theaters in December.

“She’s so well-known in terms of what she looks like and what she sounds like and how she moves, so to get that is definitely daunting,” Portman told Entertainment Weekly last month of the multidimensional role. “[We see] the toughness of who she was, dealing with what she had to go through while keeping herself together for the sake of the country and her family, and also the vulnerability and the intelligence of how she really crafted [her husband's] legacy.”

"Jackie," which premiered at the Venice Film Festival in September and will hit select theaters Dec. 2, has been critically acclaimed and is expected to do well come awards season. Some have even predicted that this could be the film that wins Portman, 35, her second Oscar.
