Russell Crowe and Emma Watson took dance lessons together

Actor Russell Crowe and Harry Potter star Emma Watson took dance lessons together while filming new movie Noah to take their minds off the gruelling shoot.

The Gladiator star shares screen time with Watson in the Biblical epic, but many of their scenes were so exhausting it left them completely drained.

The pair decided to team up and take classes in how to dance the Viennese waltz to get them away from the pressures of the shoot, and one day out ended in a booze and caviar binge.

Crowe tells Britain's Event magazine, "We had a great relationship. We did Viennese waltz lessons every Sunday to take us away from the brutality of what we were doing on set. And then we would go and have a cup of tea, and one day we went and had a steak and a bottle of wine and then ended up at the Russian tea house and had some caviar and vodka."
