Simian Cinema

Simian Cinema is a unlockable mode in Ape Escape 3 that contains short films. To unlock, the player must film the performing monkey(s) with the Pipo Camera. If the player is spotted by the monkey(s) or captures them beforehand, they will not unlock that specific Monkey Movie. Once Free Play Mode has been unlocked, the player can go back any level and film any monkey(s) that they missed. All the Monkey Movies can be seen at the Simian Cinema at the Shopping Area.

If the player successfully films and watches all 20 movies, they will unlock the Monkey Movie Studio. In this mode, the player can either edit a Monkey Movie or create their own.

Allusions to the Metal Gear series
Simian Cinema contains two secret Metal Gear related Monkey Movies based on Mesal Gear Solid. To unlock, the player must enter the password "2 snakes" at the title screen. To enter the password, the player must hold down the L1, L2, R1, R2, and Start buttons at the same time. Entering this password also unlocks The Two Snakes cutscene.
