After four seasons in the arctic apocalypse, the AMC/AMC+’s sci-fi series “Snowpiercer” will come to an end later this summer. At San Diego Comic Con, cast members Daveed Diggs (“Andre Layton”), Mickey Sumner (“Bess Till”) and Mike O’Malley (“Sam Roche”) gathered with executive producers Paul Zbyszewski and Christoph Schrewe to reflect on four seasons of the gripping and timely show.

Overall, one could argue to biggest shift and change of the series in its final season is that the action is no longer confined to the train on which the characters are forced to live. Zbyszewski and Schrewe spoke to the decision of bringing “Snowpiercer’s” characters into a new environment. “the family was getting along at the end of Season Three.” Therefore, a new setting and sources of conflict allowed for new rifts among the train’s passengers to arrive, as well as new characters and outside forces to push the people viewers have gotten to know over the past three seasons. It’s also a stunning departure from Bong Joon Ho’s 2013 film of the same name that “Snowpiercer” is based on, demonstrating not only the imagination of the series’s writers but the richness of the world they’ve created.

Snowpiercer’s Cast Reveal Biggest Character Transformations and What They Took from Set

The cast identified what they found to be their characters’ biggest transformations and surprises over the course of the show. For Diggs’s Layton, it was has shift from being an idealist to how becoming a parent made his character slightly more selfish, albeit for the love of his child. O’Malley detailed his Roche’s arc throughout the series, transforming from a rank-and-file enforcer into one of Layton’s lieutenants in his new police force. For Sumner, it was Till’s capacity for love that surprised her most.  “Her depth of her love, her romantic love for Audrey and her love for her friends…her love for the train.”

Love was palpable at San Diego as well between the cast and producers. Each of them cited how much they’ve missed one another since wrapping “Snowpiercer“. Furthermore, they expounded on how filming during the COVID-19 pandemic brought the team closer together as they shot the show in a locked down Vancouver, Canada. When asked what each cast member would take from set, Diggs revealed the incredible detail of the art department, that there was a prop on set that was a full manual on the Snowpiercer train’s operation. O’Malley said he’d like Roche’s lunch pail from the series, since its existence helped me craft the nuance of his character’s background. Sumner shared that she was able to keep all of Till’s post-apocalyptic, high-fashion wardrobe, an admission that left the sartorially minded-salivating.
