Henry V is a 2012 British television film based on the play of the same name by William Shakespeare. It is the fourth film in the series of television films called "The Hollow Crown" produced by Sam Mendes for BBC Two covering the whole of Shakespeare's Henriad. It was directed by Thea Sharrock and stars Tom Hiddleston as Henry V of England.
There are more than five films in total in the series of television films called "The Hollow Crown".
It's neither correct/incorrect because we don't know how many films there are exactly, we just know there are at least four, maybe there are only five. It's difficult because the text mentions the "fourth" film, so perhaps the system used this to determine there were only four in total.
