is the halo movie going to be about halo 1 or 3?

i read the movie description and it seems to be about halo 1 however when i searched it only some people said it was about halo 3

If it goes ahead, the first movie will be a prequel to the original ‘Halo’ game, which explains the origins of the characters while the second and third will develop the storyline from the best-selling games.

I have heard of a prequel as well. All depend on how it goes and what Spielberg does with it since it sounds like he will be at the helm of it.
