I remember that there were some discussion in old forum about titles including for example director's name before the actual title, but I cannot remember what was the common agreement.

Is the correct title for example Alfred Hitchcock's The Birds or just The Birds?

Quoting ya_shin:

Quote:
The Title must be taken from the movie's credits. Whatever you see there, is the Title.

Unless the DVD title on the cover is different when whatever you see on the cover is the title and what you see on the movie is the Original Title

And then what if the Director's name is in (slightly or much) smaller print than the title?
I think the title on the movie credits should have precedence, since the DVD is the medium, not the message. And of course, sometimes the movie title is translated on the cover, and then you use that, with original title. But just creating a new title by combining the title with other information that is on the cover is arbitrary.
