The Astronomical Journal, 2017•iopscience.iop.org… = 10000 planetary anomaly is striking. We present a simple formalism to estimate the
sensitivity of other Hollywood events to planets and show that they can lead to detections
close to, but perhaps not quite reaching, the Earth/Sun mass ratio of $3\times {10}^{-6}$ …
Hence, while there is no doubt that OGLE-2017-BLG-0173Lb is a very low-mass-ratio
planet $q\lt {10}^{-4}$ …
