The story lines are similar, following a couple who risk their lives for missions. But the biggest difference is their knowledge of one another. In the movie, Pitt and Jolie don’t know that their partner is a spy, too—that is, until they’re assigned to kill each other. But in the Prime Video series, Glover and Erskine are well aware of their partner’s professions. In fact, it’s the whole reason they’re introduced in the first place.
Another difference is the on-screen relationship between the stars. In the movie, Pitt and Jolie have been married for six-ish years and, therefore, have developed an understanding of each other. But in the Prime Video series, Glover and Erskine are just meeting for the first time. They’re learning about each other’s pasts and families while carrying out dangerous missions.
To top it off, Glover and Erskine work as a team to carry out missions—whereas, in the movie, Jolie and Pitt work against each other. This offers a unique on-screen dynamic between the two main characters. Although they’re still unsure of each other, it’s clear that romance will become a theme as the show progresses.
