The actors are also learning about each other. They are revealing themselves to each other, sharing, in greater and greater amounts, their personal feelings. Henry Fonda told me that on the first day of shooting a Sergio Leone movie, he had to shoot a sexy love scene with Gina Lollobrigida. No rehearsal. Right to it. Actors are very different about love and sex scenes. Some shy away from them. The wife of an actor I worked with wouldn’t allow him to do them. I know that if an affair develops between two actors, it will usually begin on either the day I stage the love scene or the day I shoot it. An actor who must remain nameless wanted to be in on the casting of the woman who was going to play opposite him. When I asked why, he said he had to be able to relate to her sexually if he was to play the love scenes properly. So I asked him, what if the script called for him to kill her? Would he have to relate to her murderously in order to play the part? Things were a little testy between us for the next few days.
