World UFO Day is observed annually on July 2 to encourage public interest in unidentified flying objects, space exploration, and the possibility of extraterrestrial life. While scientific evidence regarding alien life remains a subject of ongoing research, the theme has inspired filmmakers around the world for decades, resulting in some of cinema's most memorable science fiction productions.
Hollywood and Bollywood have both contributed significantly to the genre by creating stories that combine adventure, emotion, suspense, and imagination.
