It's definitely not unique to Hollywood... Before I switched to infrastructure development I ran a Linux engineering group and among other things handled production support escalations. The job was often finding the actual problem while gently dissuading my customer the issue wasn't a pet theory and/or something they just Googled. In fact sometimes the escalations came specifically so I could weigh in on root cause after joining the bridge because the various parties couldn't agree.

A favorite was someone to run free and declare the system was "out of memory and must be swapping". It recurred so often I think that theory passed from group to group like a treasured heirloom until we wrote a FAQ on the subject. Fortunately in my opinion getting ops and development to work together built mutual respect for respective skill sets.
