We have used iodine intercalation to alter the interplane interaction and the anisotropic resistivity tensor of the oxide superconductor Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub {ital x}}. Real-space transmission electron microscopy images confirm that iodine is epitaxially intercalated between the Bi-O bilayers. In the normal state above {ital T}{sub {ital c}}, the metallic CuO{sub 2} plane sheet resistance is unaffected by intercalation, while the out-of-plane conduction is dramatically changed from semiconductorlike to metalliclike. This result is inconsistent with some of the theoretical predictions based on holon-spinon scattering.
