Given the following context:

The story begins in 1957 in the star-filled skies above California's Mojave Desert. It is a special night for noted astronomer Ted Lewis, who is preparing a special anniversary dinner with steaks for his beautiful, adoring wife Lana while observing the annual meteor shower of the Perseids. In another part of town, Tammy, a waitress at small local diner with big plans for the future, looks out her window and is excited to see a shooting star, which she takes as a good sign for her dreams.
Suddenly "something shoots overhead and crashes" in the nearby mountains. Assuming it is a fallen meteorite, Ted wants to investigate in person. He reaches the supposed meteorite, which turns out to be an alien spaceship. Then his body is usurped by Urp, a well-meaning, tall, and metallic alien. Urp has discovered that the other passenger of his ship, the one-eyed monster known as Ghota has escaped. He needs to retrieve it and uses a human body to blend in with the locals.The Ghota consumes people in order to grow, multiply, and conquer. Its unquenchable appetite could mean the end of life on Earth. Urp is the only one who knows how to stop the hideous extraterrestrial. He enlists the aid of Tammy, the only human in town willing to believe and trust in his mission. The local police - including Chief Dawson and Officer Vern - are confirmed skeptics and offer little help. Together, Urp and Tammy must hunt down the Ghota and neutralize it before it consumes all the local inhabitants and uses the human fuel to multiply and conquer the world.
Urp and Tammy eventually fall in love. But at the finale, he is compelled to return to his home in space and she is left longing for his company. While she remains on Earth, she finally leaves the small town to go in search of her own destiny.

What is the full name of the person whose body is usurped by an alien?
