The Rage
Super Freak
In some twisted way I wonder if it has to do with movie piracy. Release it in the US last so there is no chance for these smaller markets (in terms of revenue) to get good quality pirated films. I suspect copyright laws in Asia aren't as strict as they are in North America. Maybe it also creates buzz.
It's really only a week, not a huge amount of time, certainly not enough to make it anything but a calculated move.
That seems like it would be reverse logic. If it hits Asia first in April, you'd think that because of the lax copyright laws would make them want to pirate the film for distribution MORE. However usually theater pirate copies aren't the problem as much as they used to be, its the film screeners that get posted online that pisses off the studios the most.
