Vaults were set to appear, and play a key role, in the canceled Fallout movie.
We are introduced to Vault 13 in the very first scene. It is a scaled down replica of Los Angeles complete with climate control. As the film treatment informs us that all the vaults were identical, it is fair to assume that all the South Californian vaults would have been too. This is reinforced by the fact that Hero shows unparalleled knowledge of Vault 13, and this later saves his life in Vault 8.
It is also fair to presume due to the vaults' identical designs that all of them produced the LA Times newspaper.
Two vaults were set to appear in the Fallout movie.
