Shane returns to the DLO with her box of belongings, which means the movie must take place immediately after the previous movie ("From Paris with Love").
Crystal Lowe (Rita) was pregnant, but not yet showing, with her first child during the filming of this movie.
Martha Williamson shared in an interview that this storyline was based on her own experiences of finding out the dad that raised her wasn't her biological dad.
In early scenes in the DLO, Shane's shoes change several times--different heel styles.
