The idiom "the other way round" can be used for claiming that the opposite of what just has been said is true. For example:
In the following usage of "the other way round", simply, what is the opposite of what?
I = Interviewer P = Professor
I: On today’s programme, we’re going to talk about women’s films, and here to talk to us is Janet Shaw, professor of Media Studies at Midland University.
I: First of all, Professor Shaw, what ARE women’s films? Are they all about romance and relationships?
P: Well, they aren’t just one kind of film, in fact, there are lots of different kinds of women’s films. Yes, a lot of them are about romance and relationships. Women’s films focus more on the people and dialogue, and men’s films often focus more on the action.
I: So action films are men’s films.
P: Well, not necessarily. Some women’s films are action films too – but they take a women’s point of view, and the main characters are often women – characters that female audience can identify with. For example, there was the film Thelma and Louise, about two female criminals, or the science fiction film Alien, with Sigourney Weaver.
I: Ah. Are the main characters always female?
P: No – a lot of women’s film have lead actors like Nicolas Cage or Hugh Grant or Mel Gibson – male actors who a lot of women find attractive.
I: Uh huh. Are women’s films actually made for women? I mean, do the film makers sit down and say ‘We’re going to make a women’s film here’?
P: Yes, they often make a story which they think women will like. But often it’s the other way round. For example films from classic literature, such as Pride and Prejudice – these could be called women’s films.
I: Because they focus on characters …
P: Yes, characters and relationships – more dialogue, less action.
I: OK, and finally – do women watch only women’s films?
P: No – that would be impossible! There are far fewer women’s films than men’s films, so women have to watch men’s films, too. And of course, people aren’t just stereotypes. There are a lot of men who like women’s film. And a lot of women who actually prefer men’s films.
I: OK … and what about you?
P: Ooh, now that’s a difficult question! Actually, I prefer reading books!
I: Ah ha, yes, I see. OK, well, thank you very much for joining us today.
P: You’re welcome.
