I see you're looking for a guide related to "Jurassic Park 1" and possibly a reference to "Tamilgun," which might imply you're looking for a way to watch or understand the movie "Jurassic Park" (1993) directed by Steven Spielberg, in Tamil or through a specific platform/app named Tamilgun. However, "Tamilgun" doesn't directly relate to official movie platforms or well-known movie databases but seems to refer to a website or service that might provide movie content.
