When Tania and Vassili finally consummate their passions, they do so surrounded by their sleeping comrades. Weisz says she was no more intimidated by her love scenes than Tania would have been in real life. There is no privacy in war. Tania and Vassili knew they were not alone, but they were not concerned about possible prying eyes. She and Law have a rather explicit love scene surrounded by dozens of extras.
Actors are never alone for their love scenes.
There are always directors, camera people, sound people and a myriad of technicians. To add a few more extras and actors is inconsequential. It doesn't make the scene any easier or any less awkward and unrealistic. Weisz found filming Enemy at the Gates even more taxing and physically gruelling than helping Brendan Fraser save the world from an undead Egyptian high priest in The Mummy and its much-anticipated sequel, The Mummy Returns, which is scheduled to open May 4. The special effects crews and technical people work harder than the actors on the Mummy movies.
