That guy on the right is Elendil in the movie, while in the book the king there
is Anarion (although interestingly, only his son became king after last
alliance, not him).
It was built by king Romendacil I (I think) to warn off the Easterlings and bad
Northmen not to enter mighty Gondor. Isildur's lands, goverened by Minas Ithil
were on the east bank of Anduin, while on the right was Anarion, whose lands
were governed by Minas Anor (later Tirith). Osgiliath, of course was straight
on.
The movie isn;t that wrong- Elendil's realm of Arnor is still westward of the
Argonath.
There is but one task remaining in Arda-we,the Dragons of Valinor will make it happen.
