Just saw Interstellar.
When Cooper gets his faceplate cracked and is disabled by the in-rush of ammonia atmosphere my suspension of disbelief broke.
Why?
Because for a small leak in a poisonous atmosphere you turn up suit pressure to above ambient. In fact it's a good plan to have your suit set slightly above ambient pressure just in case there is a puncture.
NASA's A7L had controls for suit pressure and it was intended for vacuum only.
