The cliche elder, mentor, or expert who comes to provide wisdom...
Ha ha...
This seems like a cool thread to make, so I'll make it.
Recall all those classics from the 90s and 80s and before. Remember the cliche expert who arrives on the scene at some point to impart knowledge to the troubled protagonists combating the supernatural forces..?
It usually happens in a pattern. We usually see this expert at the beginning of the film. We see them briefly, then they fade away until later on in the film when they are needed to save the day, or provide some background on the menacing forces at play. And, mind you, it's often knowledge that no one on Earth should really know, but somehow these experts possess said knowledge anyway. Of course, we can always simply tally it up to story conceit. But it sure is fun!
Let's run through some films:
The Exorcist - Father Merrin
Arachnophobia - Julian Sands's doctor character
Poltergeist - Tangina
Jurassic Park - The Australian raptor expert
Child's Play - the voodoo guy who knows about Chucky and how to kill him
Wolf - the character who provides Nicholson's character background info on the wolf entity
Dolly Dearest - (I barely remember this one, but there's one involving info on an ancient goat)
Jaws - Quentin
Damn, I had more examples but for some reason they currently fail me off the top of my head. Anyhow, you guys and gals are free to provide some as well.
The wise elderly expert is oftentimes someone we see in the first act, who is gone for most of the second act, and then they come back to impart knowledge or to rescue the protagonists, or to help the protagonists rescue themselves, and they often are killed by the very menacing force they were called upon to assist against. They are often mysterious characters who have had a past experience with the antagonist or menacing force, perhaps now having a score to settle. Either they defeated the evil, or the evil defeated them in the past.
They make the audience feel safe and comfortable the moment they arrive, as if their presence and knowledge is enough to provide sufficient refuge from the danger in question. It happens in varying ways, like in the case of Tangina, or other characters in other Horror films who the protagonists eventually find who happen to have knowledge on the antagonizing force (ha ha... I just thought of King Willy and the Gary Busy character from Predator 2).
Who are some more characters? Who are your favorite examples of this elder-expert story convention? Who did you find most impressive? It doesn't have to be all Horror, incidentally. I'm sure there are other genres, like Sci-Fi or Fantasy (or perhaps even Action or Drama), with characters who are examples of this cliche.
I'm not a control freak, I just like things my way
