Reservation Road (2007)

Dwight Arno (Ruffalo) is an attorney who is divorced from his wife Ruth (Sorvino). Ruth controls custody of their son Lucas (Alderson), while Dwight maintains visitation rights. Dwight and Lucas are at a baseball game when Ruth calls, informing Dwight that he is late with returning their son home. Dwight drives Lucas home in a hurry, thinking he might forfeit his visitation privileges. When he loses control of his vehicle, he accidentally hits a young boy, Josh Learner (Curley), who is standing by a roadside. Aware that he has struck the boy, Dwight continues driving on.
