Ptushko is frequently (and somewhat misleadingly) referred to as "the Soviet Walt Disney," due to his prominent early role in animation in the Soviet Union, though a more accurate comparison would be to Willis O'Brien or Ray Harryhausen.  Some critics, such as Tim Lucas and Alan Upchurch, have also compared Ptushko to Italian filmmaker Mario Bava, who made fantasy and horror films with similarities to Ptushko's work and made similarly innovative use of color cinematography and special effects.  He began his film career as a director and animator of stop-motion short films, and became a director of feature-length films combining live-action, stop-motion, creative special effects, and Russian mythology.  Along the way he would be responsible for a number of firsts in Russian film history (including the first feature-length animated film, and the first film in color), and would make several extremely popular and internationally praised films full of visual flair and spectacle. Michael Trcic (born 1960) is an American sculptor best known for his paleontological models of dinosaurs.  He worked for many years as a special effects artist for films and television programs, and was one of the lead animators and puppeteers for the famous "Tyrannosaurus rex" model featured in Steven Spielberg's 1993 film "Jurassic Park".  He has also worked in television animation, including for Discovery Channel's 2002 documentary film "When Dinosaurs Roamed America".  For models and other artwork outside of special effects, Trcic commonly consults with paleontologists in order to achieve a high standard of accuracy for his work.  His sculpture has been compared to that of Brian Cooley, but with a "somewhat more traditional" style.  He has provided dinosaur sculpture work for a variety of media and institutions, including IMAX, The University of Chicago, The National Geographic Society, Disney, and the Arizona Museum of Natural History, where his life-sized bronze "Dilophosaurus" sculpture is featured.  His statue of the sauropod dinosaur "Jobaria" can be viewed at the Navy Pier of Chicago, Illinois.  Trcic's work has also been published in a variety of written media, including Random House's book "Hunting Dinosaurs" and the magazines "Earth Magazine" and "Prehistoric Times".
