Both Avery Pizzuto and her character, Susan, have Type 1 Diabetes. Avery has also gone on her own pioneer trek. She was able to use her own experiences, as a diabetic on trek, to bring her character to life.
Both Clint Pulver (Brad) and Spencer Marsh (Lehi) had met each other previously while trying out for the role of Elder Kestler in the remake of Saturday's Warrior (2016). Pulver would edge Marsh out for the role after several callbacks. In Trek they play best friends.
In addition to acting Stefania Barr, who plays Anna, is front-woman of alt-rock band "Shrink the Giant."
Stefania Barr's band is featured in the soundtrack.
