In true-life dramas, you have to do so much research. It's a big responsibility to make sure things are as correct as possible. In 'Robin Hood', you have more artistic license - it's all action, adventure and reaction. This gives everyone a chance to make their characters their own and to make them believable.

Working with franchises can be challenging, but at the same time I really did enjoy working on 'Star Wars,' for example, and I have done a lot of 'Dungeons & Dragons' games, but I still enjoy it very much.
