The scientist Peter Venkman (Bill Murray) from Ghostbusters has a very interesting personality, he is always flirting with female clients and is more laid back it seems than the other Ghostbusters. While he is very snippy and cynical would it be correct to consider his character in the movie a narcissist?
I think the answer to that would be no. Narcissism is a serious psychological disorder. The symptoms, according to the Diagnostic and Statistical Manual of Mental Disorders include:
Narcissists can be quite sadistic in their need to elevate self by putting others down. Venkman had some ego issues, but he was not without empathy - he bonded with his team and he did develop a relationship. The audience liked him. A narcissist does not make a likable character.
I'm going to say, Possibly. Maybe not intentionally, but I think at that period in Bill Murray's career, when he was at the top of his game, most of his characters exhibited the same type of personality. His acting really was pretty one-dimensional, almost like Keanu Reeves. Murray was the lovable loser with the big ego, always ready with a funny quip. He was the same guy in Stripes and all the other movies in that time period, when you think about it.
Since most of his characters were pretty identical, it's safe to say that much of Murray's self is portrayed in those characters. And he probably was a bit narcisstic at that point in his career as a rising star. Maybe he didn't exhibit all of the signs, but there were almost definitely some narcisstic traits evident.
Full of himself, yes. He's the common english/slang use of Narcissist, but not the clinical use.
And even that's contentious, as there is opposing views on Narcissistic Personality Disorder being a valid issue, if NPD should be folded into a broader category, or if it should stay as it's own diagnosis. (2010 arguments over the DSM 5 changes to Personality Disorders).
But the simplest way to see if Venkman fits the NPD diagnosis is the 5 point test:
Generally, Venkman does not suffer from identity issues, is confident in his self-direction (until his funding gets cut, then he quickly moves on to loftier goals), and has no issues with Empathy or Intimacy. See his relationship with Dana Barrett, both before and after they break up.
He does have some Antagonism issues, but nothing that's overly aggressive (and he's always right, so he's not making things up). His personality is pretty consistent, but both of that's normal for a 1980s New Yorker (his socio-cultural environment). Drugs and injuries are not a factor here.
But the biggest thing is that none of his personality impairs his interactions. He's a fully functional, normal adult male with mostly stable friendships, business relations, and romances.
