Shooting had a 3-month gap (jumping from summer to winter once more) while Shawn Elestren struggled to find an actor for the role of Lucky. Eventually John Kerr agreed to to do the part.
Although not named on-screen the character played by John Kerr is actually called 'Lucky'. This is meant to be a counterpoint to the mostly unseen character of 'Happy' in Shawn Is on the Trail (2012) as well as counterpoint to Shawn himself who repeatedly said that he did not believe in luck but in random chance.
Lady Iris Isabella Wheeler tells Shawn that 'The Island is Calling', which is the tagline to Shawn's Final Countdown (2011).
Instead of recycling and cropping old footage from 1.78:1 to a 2.35:1 aspect ratio Shawn Elestren opted to re-shoot scenes from previous movies for the flashback sequence, all except for the shots from Shawn Is on the Trail (2012) which would have been impossible to shoot again.
Cyres Dorward was due to return as T-Bone and had filmed half of his scenes before quitting the production without explanation. Michelle Samantha Roberts replaced him as a new character. T-Bone is consequently explained as being away on holiday.
