Chusanachoti initially came up with concept of Shelldon in 2001, but it took him until 2008 – and a US$2 million investment from family and friends – before he was signed up for his first series. It proved an overnight success. After only two series of 26 episodes, Shelldon is now shown in more than 100 countries and dubbed in 30 languages. Although the original series was produced mainly in Singapore, around 90% of season two was made in Thailand.
