This season is based on a mixture of the first (Stormbreaker) and second (Point Blanc) Alex Rider novels by Anthony Horowitz. In this episode, during the bike chase scene where Alex chases Crawley's car from the scene of his uncle's murder, there are a few Easter eggs to the books (it is unclear if these are intentional or not). At the start of the Stormbreaker book, during the original bike chase scene, Alex is chasing a removals van, this is also the case in the Stormbreaker (2006) movie. At 34:44 there is a large white removals van driving behind Alex as he is tracking Crawley's car. Additionally, at the start of Point Blanc, Alex gets up to mischief by tracking a drug dealer to a canal boat and then uses a crane to pick up said boat. At 34:54, during the chase, Alex rides alongside the canal and multiple canal boats. A crane can also be seen in the background at 35.00.
This first season was shot over a period of six months.
