Was sad to hear this. His editing on Alien
is of course legendary, but some of the stuff he did on Alien 3
is among my favourite moments from the whole series; the intercut funeral/Alien birth scene and Ripley's death in particular are wonderfully edited sequences.
Also really enjoy his bits in the Wreckage and Rage
documentary, especially all the rather frank stuff towards the end that got cut out in the original DVD edit
