Finding My Peace

Molly Brown, creature creator and concept artist, share concept art of the SM-13 submarine, the titular Iron Lung. The details about giving it monstrous qualities to match the monster are especially fascinating.

Grimm Craft revealed their work on the project with creating a physical and a digital model of the interior of the sub.

"One particular piece I’m proud to have built for the film was a scale mock-up of the SM-13 submarine which I later nicknamed “the Dollhouse”. It consisted of three parts that could be opened for a side profile of the interior to allow Mark and the crew to plan camera shots.

In the beginning of production planning, I would spend time in the original game from @duskdeveloper to study the feel of the submarine as well as all of the details for the interior. I then modeled my full size interpretation of the set on my tablet using @shapr3d_official and printed the scale mock-up with PLA and used various paint techniques to better match it to the rusted aesthetic.

During early concept design, we discussed how the submarine would traverse the “blood ocean” floor. We eventually agreed on cylindrical screws, also commonly called a “screw tank”, that would make it feel more plausible compared to traditional “tank treads”."
