On its opening weekend in the United States, it went to number one, becoming the film to finally end the reign of James Cameron's Avatar (2009), which had sat at the top of the box office for seven consecutive weeks.
This is the fifth film adapted from a Nicholas Sparks novel. It is also the first of two to be directed by Lasse Halström and the first of two to be released in the same year; The Last Song (2010) was released less than two months later.
The trivia item below may give away important plot points.
This is a list of the biggest differences between the movie, and the book that it was based on: 1. In the book, Alan is Tim's brother, not his son. 2. In the book, Tim had melanoma, not leukemia. 3. In the book, Savannah reveals that she was almost raped in her freshman year of college; the movie makes no reference to this. 4. In the book, Savannah was a brunette, with a small gap in her teeth; in the film, she is a blonde with no gap in her teeth. 5.

In the book, John serves in Iraq, not Afghanistan, and often trains and/or works in Kosovo and other places not mentioned in the movie. 7.

In the book, Savannah and John make love twice (in the same night), not just once (like in the movie). 9.

In the movie, there is a party at Savannahs' parent's house after September 11th; there is no such party in the book. 14.

The kissing scene inside the unfinished house takes place at night, unlike in the movie. 16. In the novel, Mr. Tyree is never invited to meet Savannah's parents. 17.
