Three different Marvel Cinematic Universe superheroes are in this film: Chris Evans, who plays Captain America in Captain America: The First Avenger (2011), The Avengers (2012), Captain America: The Winter Soldier (2014), and Avengers: Age of Ultron (2015); Anthony Mackie, who plays Sam Wilson/Falcon in Captain America: The Winter Soldier (2014); and Chris Pratt, who plays Peter Quill/Star-Lord in Guardians of the Galaxy (2014).
Most of the magazine articles depicted at the beginning of the film are closely related to the events in the plot: "Change too for your man" (Ally constantly changes herself to please others), "Stalking your ex" (the main part of the plot involves Ally contacting old ex-boyfriends), "Does he only want your bod?" (Colin is at first attracted to Ally physically), "Less than perfect: A daughter's story of pleasing her mother" (Ally settling for the wrong guy to make her mother happy), "Be a dude -not- a douche" (the evolution of Colin's character as the plot evolves), "When your sister is just plain better than you" (Daisy is doing better in the relationship front than Ally), "Decorating your bedroom with him in mind" (the one seen the longest, it foreshadows Ally having to accommodate to Colin's presence in her apartment during his hideouts).
