Was this the first movie to use this type of humor with action mix?
Movies before this were either full action or straight up comedy.
I know Arnold had some one-liners during the 80s and early 90s (Predator's "stick around" stabbing, multiple one-liners in T2, etc)
But True Lies keeps itself as a very serious toned R rated action film with lots of humor (no Airplane!, Naked Gun type of humor, just enough to not take us away that it's an action movie first).
It's all over the movie, it's so clever and fast-paced and it's used nowadays in movies in the current James Bond and Mission: Impossible movies... I would even dare to say that this balance is being used in Marvel's PG-13 movies, but not as perfect as it was used in True Lies.
Which movie had a similar tone to True Lies before it came out???
James Bond during the late 80s was way too serious, Roger Moore's was mostly a parody and Connery was just delivering one-liners.
I can't think of anything else to compare it to pre-1994.
