[[WMG:The main character is David Callan from ''Series/{{Callan}}'']]
* Same actor, lot of similarities between the two shows.
** Also, we never learn the details of Robert [=McCall=]'s DarkAndTroubledPast. Who's to say he wasn't Callan?
** Also, the name 'David Callan' wasn't the character's real name, which is not revealed in that show.
** Unlikely however as Callan was a working class man whose parents were killed in [=WW2=] whilst [=McCall=] is very obviously upper class whose parents had a different fate.
----
[[WMG:Season 1 recurring antagonist [[ObstructiveBureaucrat Jason Masur]] is actually Arthur Weisfeld (a.k.a. Artie Nielsen from Series/Warehouse13)]]
* Again, [[Creator/SaulRubinek same actor]] and somewhat similar characters (intelligence officers during the UsefulNotes/ColdWar).
----
[[WMG:Given their nearly similar age and skillset...]]
* [=McCall=] and [[Film/{{Taken}} Bryan Mills]] were a part of the same team, and because of some world-threatening event [[CrisisCrossover they must reunite]].
** Though given [=McCall=]'s age, perhaps he was Bryan's mentor as well as his teammate?
* Applicable to the film: In a similar vein, given the age difference and similar ability to improvise, [=McCall=] was trained by Series/{{MacGyver|1985}} when [=MacGyver=] was still an active intelligence agent.
