As requested by @ScottPress in TOMD, the quiz I wrote for a friend. Its supposed to a fairly challenging set of HP trivia questions from both the books and the films, for normal folk who aren't quite as invested as folk on here are.

1. What is Professor Quirrel’s first name?
2. How many times did Gilderoy Lockhart win Witch Weekly’s Most Charming Smile award?
   
3. What was Regulas Black's middle name?
4. What is the name of Rita Skeeter’s unauthorised biography of Albus Dumbledore?
   
5. What is the incantation of the Leg Locker Curse?
   
6. Which quidditch manoeuvre requires the seeker to go into a dive pretending they have seen the snitch, aiming to have the opposing seeker crash into the ground?
   
7. In Harry Potter and the Order of the Phoenix, what sort of creature did Harry, Hermione, and the Weasley’s have to clear out of a set of curtains inside Grimmauld Place?
   
8. How many actors have played Albus Dumbledore on screen?
   
9. In which of the 8 main Harry Potter films does Newt Scamander make an appearance?
   
10. When Harry views Snape’s memories in the Deathly Hallows he sees the moment where Snape defected to join Dumbledore’s cause. What were the first words that Snape said to Dumbledore at that meeting?

9. Either it's a trick question and he doesn't appear, or it was at Fleur and Bill's wedding. But I'm not sure

Checking answers...6/10

 

My turn,

Spoiler

1) Quirinus
2) 5, I think
3) Arcturus, unless the typo is voluntary in which case the answer is "there's no Regulas Black and this is a vicious trap"
4) The Life and Lies of Albus Dumbledore, don't think she went with the middle names
5) Locomotor Mortis, took me a while to remember the first part
6) Wronski Feint
7) Doxies
8) 3, Michael Gambon, Jude Law and the first one who died and I never remember the name of.
9) None
10) Please don't kill me.

Checking answers, 7 or 8 depending on if you'd accept the last one with a please.
Now that I think about it, there was probably a teenage Dumbledore on a photo with Grindelwald, I should have thought about it. But Newt appeared in PoA? Huh, you learn something every day. Was it on a book cover or something?

 

6/10 for me. I got 2, 5, 8, & 10 wrong.

 

Spoiler

@Goten Askil Scamander's name appeared on the Marauders Map in the film, lurking around some side corridor of Hogwarts.

 

Spoiler

I got number nine wrong, I didn't know that at all. I'm going to have to go google that one.

EDIT: or not. What a creepy chappie. Watch him die at the end of the prequel series now for maximum incongruity bonus.

 

Spoiler

@Blorcyn yeah, him creeping around the corridors of a school at the age of 96 is a bit weird. Apparently one theory is that he's a ghost at that point.

 

Spoiler

Quirinis or something like that.

Five.

Arcturis or something like that.

The Life and Lies of Albus Dumbledore

Locomotor mortis

Wronski Feint

Doxies

At least two.

The prequels

Don't kill me.

Apparently I lack reading comprehension for question 9. Also I haven't seen the movies so I feel a bit disadvantaged.
