Reacher and Jack Ryan, despite being on the same platform, i.e., Prime Video, and belonging to the same genre (action), have managed to remain separate. Moreover, both characters' names share the initials "JR". This is why some fans continue hoping for a crossover between the two characters as they share the same streaming platform.Crossovers have become the norm in this era of Marvel Cinematic Universe movies, consisting of different characters sharing the same continuity. However, crossovers are not as easy as we fans believe them to be. Even though the two Jacks might share similarities, the two franchises are fundamentally different.Could Reacher and Jack Ryan crossover?Technically, it is highly unlikely that the two Jacks could crossover. Even though both are action franchises in which the former military protagonist is reluctantly dragged into battles, Jack Ryan regularly uncovers terror threats against the US. He works for the CIA, and thus, the scope of the Jack Ryan series is regularly larger.Reacher, on the other hand, has a simple plot; each season of the Prime Video series follows Alan Ritchson's hulking protagonist fighting the local mob boss, a shady businessman, and even government departments. The ongoing fourth season follows an Army veteran on the run from the CIA and the FBI, as he tries to solve the mysterious case of a woman who ended her life in his presence.Moreover, Alan Ritchson's character is a military veteran who doesn't have access to any support. He is popular because he is a man of the people who stands up to injustice with the support of the unlikeliest people, even when the odds are stacked against them.Jack Ryan, on the other hand, is a CIA spy. Unlike Alan Ritchson's veteran, Ryan is not a man of the people. Ryan has to constantly navigate a tense geopolitical landscape where he encounters terrorists and hostile government servants. This is why Jack Ryan regularly lies and uses aliases to cover his identity. Conversely, Reacher never lies, as he is upfront about his identity and what he is going to do.Apart from the differences in character, there is another reason why the two franchises have to stay separate.There are two reasons why the two characters will not cross over: View this post on Instagram Instagram PostThe first reason why the two franchises can cross over is that their respective source materials were written by two different authors and published by different publishing houses. The rights issues would make it challenging to crossover Tom Clancy and Lee Child's characters. Amazon MGM Studios has kept the two action franchises separate because their rights probably prohibit them from doing so.Apart from rights issues, Jack Ryan and Reacher's production teams are different. Therefore, a crossover would require the two teams to compromise and negotiate behind the scenes. A crossover would be a monumental undertaking for all involved. Plus, if a crossover were to happen, it wouldn't be a one-time affair. Which is why a crossover between these two franchises seems impossible for now.Both Jack Ryan and Reacher are streaming on Prime Video.Read More:Did the Jack Ryan TV series predict the current US strike on Venezuela?
