Guillerman argued with Ilene Andrews about the feasibility of Kong remaining on Skull Island, telling her that he had gotten too big over time and that the environment there couldn't continue to sustain him. She, however, argued that any attempt to remove Kong from the habitat would result in Godzilla coming after him.

After Godzilla decimated the Apex Cybernetics in Pensacola, Director Guillerman recalled Titan Relief Leader, Mark Russell back to Castle Bravo, in hopes of using his Titan expertise to understand why the alpha Titan was destroying random cities. He explained to Russell that they were moving Kong to Antarctica in order to enter Hollow Earth. He explained how the Hollow Earth Aerial Vehicles would be able to overcome the gravity reversal, and told him that Walter Simmons claimed he would be able to control Godzilla and even take him out if necessary. Mark, however, wondered just what Walter was building and Guillerman told him that they were looking into it.

Guillerman was present with Mark during the battle in Hong Kong, coordinating Monarch rescue and evacuation teams.
