Verisimilitude, when it comes to realistically depicting professional corporate America, is a particular challenge for Hollywood.
I think it’s safe to say that the majority of actors, directors, screen writers, etc. have never worked within a typical professional corporate job environment, or role (yes, studios are corporations, but are hardly typical). So, the perspective they bring, with some notable exceptions, is usually an “outsider’s perspective” that reduces the depictions of these jobs to their most basic of poorly-informed stereotypes.
As a result of this limited point of reference, Hollywood’s depiction of corporate professional jobs in America aligns more closely with a child’s depiction of these types of jobs. They “play” accountant, corporate lawyer, architect, project manager, IT professional, etc. the same way that a child playing these roles would...simplistically and in exaggerated ways such as pounding rapidly on a keyboard, like it owes them money, and talking, nebulously, about “the BIG account” or “the BIG case” and shouting phrases like “BUY / SELL! I need an answer NOW Bob (yes, it’s always “Bob”)!” into a telephone headset, or speakerphone.
To be fair, depictions of Hollywood actors, directors, etc., by those not within that industry, also suffers by being simplistic exaggerated stereotypes presented by an “outsider”.
