Downton Abbey star Hugh Bonneville has revealed that he and co-star Elizabeth McGovern have ‘unwritten rules’ when it comes to filming bedroom scenes.

ITV1’s new period drama is actually the third time that Hugh and Elizabeth have played husband and wife.

In 2008, they appeared together in the three-part BBC comedy series Freezing.

“Put it this way, we now have such an easy shorthand that when we’re doing a scene set in the bedroom, we know exactly which side of the bed to get into,” he told

“It saves a lot of faffing around in rehearsal.”
