Doctor Who: U.N.I.T. Files (1975)

Double bill of classic 'Doctor Who' television serials. 'Invasion of the Dinosaurs' (1975) is the last storyline to feature Jon Pertwee as the Doctor. When a group of scientists who want to return the Earth to a time before technology use dinosaurs to try and force people to flee the cities, the Doctor and Sarah Jane Smith (Elisabeth Sladen) set out to stop them. In 'The Android Invasion' (1975) the Doctor (now played by Tom Baker) and Sarah Jane believe that they are back on Earth when the TARDIS lands near what seems to be a peaceful English village. But why is the local pub deserted? And who are the spacesuit-wearing figures with guns for fingers? The intrepid pair set out to discover the truth.
