Stop thinking of it as a World of Warcraft movie and think of it as a movie in the Warcraft universe. If you actually read the article you'll see that they want to make a movie in the Warcraft universe, not a movie based off of a specific game. WoW has 3 games before it laying out story. There isn't a lack of lore at all. It at least has a better start than other video game movies.

I have seen a lot of "off of" resently, I know it has something to do with the verb, but I just dont how to use it?

anyone please give me some exmples of how you use that in conversation.

Thank you very much.

i have a tentative suggestion what it might mean to base off
is it the opposite of based on?
the strategy of the army is based off of earlier routine operations.

Usage Note:
The compound preposition off of is generally regarded as informal and
is best avoided
in formal speech and writing: He stepped off (not off
of) the platform. Off is informal as well when used to indicate a
source: formal style requires I borrowed it from (not off) my
brother.

I'd have used based on in the context.

"based off of" is the same as "based on."

I wrote this story based off of your adventures in the Canadian Rockies.I would say it's casual.

But it's not the same as "off of" cited above in the "get off of the bus."
Hi guys,

I would simply describe based off of as incorrect.

I'd say the same about off of in other contexts, too. One has to draw the line somewhere, and to me that's simply on the wrong side of the line. English-lovers, it's time to stand up and be counted!

Ah, Clive - get off ofyour high horse Emotion: stick out tongue

(By the way, I agree that's it would be incorrect in writing. But you still hear it SAID quite often. Of course, I hear "try and..." all the time too, and it causes a similar reaction in me that this one seems to be creating in my esteemed colleague.)

Sir, I will join you! Count me in as you assemble the "eradicate the based off of" army.

I'm sorry, I guess that's mainly my fault, but I like it. Emotion: big smile

I'll try and avoid it as much as possible. [A]

You are right. "Off of" is always incorrect because, the "of" is unnecessary. It is a common mistake that many speakers of American English make.
