M: Good evening and welcome to our program--A Night at the Movies. I'm Mark.
W: And I'm Anna. Tonight we're going to look at this week's new films.
M: Let's start with Beyond the Moon. It's the story of a flight to Mars that gets into trouble. A team of robots save the astronauts aboard a spaceship.
W: The movie is full of space travel.
M: Next, we have A Man's Best Friend. This is the funniest movie you will see all year. It's about a cat that can talk. If you like jokes and silly situations, this is the movie for you.
W: Oh, no. Mark. There aren't many laughs, and the story is stupid and boring.
M: Well, Anna. I think we'll agree on San Francisco. The songs are great, and the dancing's fantastic.
W: I like San Francisco a lot. It's about a girl who comes from a poor family. She works hard and becomes a famous nightclub singer. I don't usually like this kind of movie, but this was different. As you said, excellent singing and dancing.
