My uncle's a film director and went to the first night of his new film on Friday. There were three speakers, my uncle, the producer and two of the actors. The film was in French with subtitles, so the translator came to talk about his work on the translation. After the speeches, they started the film, but the projector broke! Luckily, there was an orchestra to play music at the party after the film. The conductor realized the problem and asked the orchestra to start playing immediately.
