Miles is compared to David Bowie due to having two different colored eyes, commonly known as Heterochromia. However, David Bowie didn't have this condition. He actually had Anisocoria: one pupil is bigger than the other. It was this condition that made his eyes look different colors.
Miles has Heterochromia, a difference in coloration between both eyes (in Miles' case, his right eye is hazel and his left eye is blue).
Since Jackson Robert Scott filmed this movie in-between It (2017) and It Chapter Two (2019), he appeared in three horror movies in a row.
The name Miles Blume was inspired by the names of the enigmatic children in The Innocents (1961): Miles and Flora. Blume being the German and Austrian word for flower.
This was the first horror movie released in 2019 featuring Jackson Robert Scott. The second was It Chapter Two (2019).
