According to The Official Little Ashes website, the release date for the film has been changed from March to May.
Taken from their website:
Regent Releasing is pleased to announce the theatrical opening of “Little Ashes”
in select U.S. theaters beginning May 8th, 2009
Although this news is disappointing for the U.S fans (after looking forward to March for so long) I know that it will be well & truly worth the wait for them.  From the various clips I have seen, Little Ashes looks like such a beautiful film with fantastic performances by all the actors. When I think about the day when all us Aussie fans will be able to see the film, it makes me feel so excited. I cannot wait for that day to come.
OMG! i cant wait its going 2 be so goooooooooddddddddddd!!!!!!!
love ya
