As visible on the official page, this movie is titled "Volume 3".

The current logo and poster uses "Volume 3" but under the Overview on the provided link it's listed as "Vol. 3" as well as on the title tag. Perhaps interchangeable?

Not sure what the moderator @superboy97 is talking about. The page they linked to is clearly titled Vol. 3 in both the title of the page and in the text synopsis.

There are 2 places where it is written "Vol. 3" and all the otheres are listed "Volume 3". So, we will have to wait fvor the official release of the movie to see the onscreen title.

I've linked tons of websites where it reads as 'Vol. 3' as opposed to 'Volume 3'. Titling it Vol. 3 would be more in-keeping with the previous film, titled 'Vol. 2'. Doesn't make sense to have one titled Vol. 2 and the other Volume 3? it looks weird. But if that's how you guys are running things you might want to change the title for Kill Bill: 'Vol. 1 & 2' to 'Volume 1 & 2', that's if you're going off how it reads on the official poster?

the only place it reads as 'Volume 3' is in the logo of the poster or trailer, clearly just a stylistic choice, everywhere else it's referred to as 'Vol. 3'

@SergeantTibbs @superboy97 Marvel has used both "Volume 3" and "Vol. 3" interchangeably during the marketing but I saw the film last weekend and I can confirm that the title that appears on-screen is "Guardians of the Galaxy Vol. 3." Perhaps this quoted part of the Original Title sectionof the Movie Bible should apply to this movie:

When the promotional material use slightly different titles (e.g. Twelve Monkeys vs 12 Monkeys), we try to use the title as it is written in the original on-screen opening credits.

I would be in favour of that.

Same advice for me. Here is what I was saying above:

Original Title has been updated.
