Pixar needed a hit. The DisneyThe Walt Disney Company is an American multinational mass media and entertainment organisation.-owned animation studio ruled the 2000s, but recent years have been tough.

But Inside Out 2, Pixar's latest film, has revived the studio's fortunes.

It is a sequel to a 2015 film about the inner workings of the mind of an 11-year old girl called Riley. In the first film, characters based on Riley's emotions - Joy, Sadness, Fear, Disgust and Anger - helped her deal with moving to a new city.

The sequel picks up two years later and sees a new band of emotions appear as Riley hits pubertyThe time in a person's life when they go through physical and hormonal changes, changing from being a child to being an adult. .

The film's storyline reflects one of the biggest news stories of the year: the rise of anxietyA feeling of unease or worry. It can be mild or very severe. in teenagers.

Anxiety is a feeling worry or fear about something that has not yet happened but you think might. Everyone feels anxiety sometimes, but extreme anxiety can be a medical disorder.

A survey earlier this year found that almost three in ten 12 to 18-year olds in the UK have avoided going to school because of anxiety.

Some researchers believe that such high levels of anxiety are linked to the increased use of smartphones, social media and front-facing cameras.

Yet some people think that anxiety might not be all bad. In Inside Out 2, Anxiety and the other emotions have to work together to steer Riley through life.

Can a little anxiety be good for us?

Yes! Too much anxiety is bad for us, but a little can tell us when something is not working and make us more conscientious.

No! Anxiety makes us sadder, less active and more stressed. And it can make us act on our worst instincts.
