Can you tell me how UFO's have been portrayed in movies and popular culture in the US?
<|assistant|>
In the United States, UFOs have often been depicted in movies and popular culture as mysterious and potentially dangerous visitors from other worlds. Some of the most notable portrayals of UFOs include the 1968 film Mars Attacks!, which features a UFO attacking Washington DC; the 1996 movie Independence Day, which centers on a UFO invasion of Earth; and the popular series The X-Files, which revolves around the investigation of mysterious paranormal phenomena, including UFOs. In recent years, popular depictions of UFOs have moved away from alien invasion scenarios and focused more on speculative explanations of unknown phenomena or the potential existence of intelligent extraterrestrial life.
