Hollywood films are known for taking liberties with the truth, particularly when it comes to scientific matters. Reel Science, a new film series presented by Cleveland Cinemas and the Cleveland Museum of Natural History, seeks to expose those falsities. The series will present films that “do their best to tackle natural science on the silver screen — from stoically serious blockbusters to outrageously campy cult classics — and hear from Cleveland Museum of Natural History experts as they put these movies under the microscope to determine what the filmmakers got right and what would best be classified as ‘creative license.’” Tonight at 7 at the Capitol Theatre, the series kicks off with a screening of The Valley of Gwangi, a campy classic from 1969 that involves a face-off between cowboys and dinosaurs. Introduction and post-film discussion with Dr. Michael Ryan, curator of vertebrate paleontology. Tickets are $7.50. (Jeff Niesel)
