Our mission (to view Mission Impossible 2 – 6 completely out of order) self destructed in 5 seconds when we watched a DVD of Mi:2 sourced from a local charity shop, only for Mi:3 to turn up there the following week.
So the viewing order will be 1 – 5 – 6 – 4 – 2 – 3 as far as I can recall. Or possibly 1 – 5 – 4 – 6 – 2 – 3.
Anyway, even if we do see a couple of them in numerical order, it could be a random sequence… Hopefully 6 will make more sense once we’ve seen 3, not that it really matters of course.
