Ridley Scott’s Alien: Covenant made heavy use of practical makeup effects, prosthetics and creatures during the filming process. Two creature shops, Creatures Inc. Ltd and Odd Studio combined to make those effects possible, led by creature design supervisor Conor O’Sullivan and creature effects supervisor Adam Johansen.

In this visual behind the scenes look at the practical effects work in the film, Johansen, one of the founders of Odd Studio, breaks down some of the major creature effects, including for the Neomorphs, the Xenormorph, the face huggers and body bursters, various dummies, and the alien lifeforms in David’s lab.
