In the works for a while now, the HALO movie produced by Peter Jackson and Fran Walsh, is in danger of being completely canned.

Both financers of the production, Universal and 20th Century FOX,
have pulled out of the deal, supposedly scared by the rising cost of
filming. Now the production company have found themselves out looking
for a new financer, currently undetermined. Whilst a pretty big deal,
and a slight threat to the film, it will most likely still carry on.
It’s gone a bit far and gained too much attention to be cancelled at
this stage.

HALO is set to be released late 2007/early 2008. Still quite a wait on this one.
