Josh O'Connor (Andy) accidentally found himself under a rain machine when wondering off set for a break whilst filming. He thought it was freak weather at first, given it was a clear, sunny day when he got hit by the rain. The other set he found himself on was filming an episode of the TV show Line of Duty (2012).
