Aardman differs from most other major animation studio because of its use of Lewis Newsplast to mould its characters.
This is a plasticine-like substance which is easy to mould but also keeps its shape under hot studio lights.
However, it was only made by one factory, and the Torquay-based manufacturer closed earlier this year.
This part is reassuring:
Aardman has since released a statement reassuring fans that there is “absolutely no need to worry.”
The studio said it has “high levels of existing stocks of modelling clay to service current and future productions and, much like Wallace in his workshop, we have been tinkering away behind the scenes for quite some time with plans in place to ensure a smooth transition to new stocks to continue to make out iconic productions.”
