Official Site : Just Like Heaven

Elizabeth Masterson (Witherspoon) is a dedicated, workaholic doctor who is way to busy for a life. One night, she gets into a horrible car accident and becomes a spirit stuck between heaven and earth. She doesn't know she's dead and thinks nothing has happened until she meets David Abbot (Ruffalo), a lonely architect, who rents her old apartment. David thinks he's crazy by seeing Elizabeth's spirit and tries all ways to get rid of her, but she just won't go away. Although the two are complete opposites they somehow may just form a relationship.
