Planet of Dinosaurs
Planet of Dinosaurs also known as Dinossauros Planet of dinosaurs is a 1977 science fiction film. Set in an unspecified future, the film follows the journey of Captain Lee and his crew after they crash land on a planet with similar life conditions as Earth, but millions of years behind in time. Encountering a wide variety of dangerous dinosaurs, the crew decides that its best chance for survival lies on finding higher ground and setting up a defensive perimeter on a higher plateau for refuge to wait for when or if their rescuers arrive. They soon encounter a deadly Tyrannosaurus and must figure out a way to defeat the creature and survive on the planet.
After a mechanical failure aboard the spaceship Odyssey, Captain Lee Norsythe Louie Lawless is forced to crash land on a planet with atmosphere and conditions much like that of Earth, although it is many lightyears away. As the ship sinks into the lake that it landed in, communications officer Cindy Mary Appleseth realizes that she forgot the radio in the ship and attempts to retrieve it, with the assistance of fellow crewmember Chuck Chuck Pennington. En route, Cindy is attacked and killed by an unidentified aquatic creature, prompting Chuck to return to shore without the radio.Realizing that they are stranded, the remaining eight people aboard the ship decide that survival is their primary goal and begin to explore the planet that they have landed on. Derna Lee Derna Wylde slipped while going through a swamp dropping the laser gun that Mike Max Thayer had given her in the water rendering the gun unusable. Thus, leaving the stranded individuals with one less weapon. They eventually come across a Brontosaurus, which leads them to deduce that the planet is following a similar evolutionary track as Earth, but is millions of years younger. Later, Charlotte Charlotte Speer determines that the plant life, especially the berries, is poisonous. After another dinosaur encounter, Lee decides that the best option is to climb the mountains and reach a higher plateau, where he believes the large creatures will be unable to reach them. ........
