The List have profiled JJ and added a brief interview with him.

What he says about Blood and Centurion ‘They’re both very different films. I’ve done some action/fantasy work before, but nothing on the scale of Blood. It was wonderful to see the size and ambition of the project. It truly fuels your imagination. You become a big kid again. Blood took a huge amount of time because of the enormous scale in the shoot in two different continents, Asia and Europe. Centurion was made on a much smaller budget and we shot it very quickly. So each job is always a new challenge and full of wonderful surprises.’
