He was only inside his mind, not his body. Unless he stacked up on food, how did he not starve to death whilst inside John Malkovich's mind for 8 month?
Ashmi any question
You already know the answer to this question.
shareI assumed that the body of a person is in a kind of suspended animation while in the portal.
shareHe controlled John at the time, so when John ate, he was eating.
shareOnce you enter the portal, your body merges with Malkovich's. But you still keep your own mind. Your body like ceases to exist for that period of time
sharethink we have to assume your body is in effect suspended in the ether or something
of course he could have come out after 8 months and found his other body was dead or horribly withered
but since he didn't we can assume it's the equivalent of some kind of spaceship type long term hibernation/freezing, in effect
