Rabbit Hole is a 2010 American drama film directed by John Cameron Mitchell and written by David Lindsay-Abaire, based on his 2006 play of the same name.

The film stars Nicole Kidman (who also co-produced) and Aaron Eckhart as a grieving couple coping with the death of their four-year-old son.

It also stars Dianne Wiest, Tammy Blanchard, Giancarlo Esposito, Jon Tenney, Sandra Oh and Miles Teller in his film debut.

Rebecca "Becca" and Howard "Howie" Corbett's four-year-old son Danny is killed in a car accident when he runs out into the street after his dog.

Jason tells her about a comic book he is writing called Rabbit Hole, which is about parallel universes.

Howie and Becca begin to have new activities, such as bowling and playing games, and they start to accept their son's death.

The film ends with Becca and Howie sitting in their garden alone, after all their guests have left, staring into space.

The performance is riveting because she essentially plays the entire film at two levels, the surface everyday life and then what is turning over and over again in her mind.

"[14] Peter Debruge of Variety found it "a refreshingly positive-minded take on cinema's ultimate downer: overcoming the death of a child", and called it "[a]adroitly expanded" from the stage play, "with Nicole Kidman and Aaron Eckhart delivering expert, understated performances".

While the entire play takes place in the home of Becca and Howie, the film has a variety of locations.

Past incidents, such as Becca's bad experience in the grief support group, are referred to in the play's dialogue but are depicted on screen in the film.

Lane writes On stage, Rabbit Hole is a tightly focused five-character drama punctuated with sharp, surprising flashes of aching humor.

In the movie, however, supporting roles are trimmed into near irrelevance, elbowed into the background by the spotlight focused on Becca and Howie—or, more bluntly, on Nicole Kidman and Aaron Eckhart.

Here’s what David Lindsay-Abaire seems not to understand about his own play: It’s like an atom in which the five characters are electrons revolving around the missing nucleus that was Danny....
