Good examples of twin paradox or similar:

     "Ender's Game"  Military genius is "saved" for a future battle
                              80 years pass vs. 10 years, so gamma ~ 8


     "Planet of the Apes"(1968)   Space travellers return to Earth after
                              a longer-than-expected trip (1972 - 3978)
                              (but astronauts only age ~ 1 year.
                              So gamma ~ 2006, can determine velocity ...


    
     "The Last Jedi"        A person analyzes the high-speed collision
                            using classical and relativistic physics.
                            Not really intended by the makers of the film,
                            but pretty cool application of physics.

  Bad examples:  

     "Superman" (1978)      Superman flies fast around the Earth,
                            causing ???? time to go backward ????
