For some of us, growing up watching Woody, Buzz and their friends grow up throughout the Toy Story films has been an absolute honour.
And as Toy Story 4 is showing in cinemas around the world, let's take a moment and review just how far our toy friends have come; not only in terms of character but also in their animation.
The first Toy Story film was made in 1995, and if that doesn't make you feel old then we don't know what else will.
It was Pixar's first full-length, computer-animated movie and, for the time, was one of a kind – nobody had seen anything like it.
According to a video going viral on Reddit called 'How Pixar's animation has evolved over 24 years', it took 117 computers, running 24 hours a day to make the original Toy Story. Each frame took 45 min to 30 hours to render depending on how complex they were and sometimes the animations were so tricky that creators had to invent special software specifically for the film.
But looking back on the original film which was made 24 years ago and comparing it to the quality of animation movies today, you can now see how much technology has improved.

For example, its creators hadn't quite yet figured out how to make human characters because animating clothes was too complicated, which is why there are a lot of arms and leg shots mainly from the perspective of the toys in the first film. They also showed a lot of the human characters at night time so that the mistakes in their faces couldn't be noticed.

Another Pixar great, The Incredibles, marked the first film with a fully human cast, and even though that was made in 2004, there is a massive improvement to be seen.
Now, 24 years after the original Toy Story was released, the sequel is doing a lot of things the first one couldn't. Seeing it side by side is astonishing.
