We find that the Hall effect resistivity ($\rho_{xy}$) of thin films of \lsmo\ varies as a function of the angle $\theta$ between the applied magnetic field and the film normal as $\rho_{xy}=a\cos \theta + b\cos 3\theta$, where $|b|$ increases with increasing temperature and decreases with increasing magnetic field. We find that the angular dependence of the longitudinal resistivity and the magnetization cannot fully explain the surprising term $b$, suggesting it is a manifestation of an intrinsic transport property.
