Emma Watson credits her time on the Harry Potter series with giving her the stamina to withstand the gruelling shoot for new blockbuster Noah.

The actress dealt with a number of difficult processes on the set of director Darren Aronofsky's biblical epic, from working with green screen special effects to standing outside in the cold and rain for hours on end, and she is convinced her work on the wizard film franchise helped prepare her.

She tells Britain's Hello! magazine, "It's useful having had a history of working with special effects and also in terms of stamina. I am used to having to do the same thing over and over again in order to be able to get technical things right. I am used to being outside in the freezing cold for hours and being soaking wet and rained on then having to run and then cry... It can feel overwhelming and I have to remind myself it's never, ever going to be as full on as it was with Harry Potter."
