I don't know the name of a movie about a gorilla and a girl. However, there were many movies that depicted the friendship and interaction between humans and animals, such as Zoottopia, WALL-E, and Life of Pi. If you're interested in these movies, you can tell me which genre you prefer. I'll try my best to provide you with relevant information.
Definitely not. 'Tag' is a work of fiction. The story was crafted to entertain and make people laugh, not to retell real events. It's all about the creativity of the writers and directors.
Tag is purely fictional. The plot and characters were invented by the filmmakers to provide an engaging and fun cinematic experience. There's no real-life inspiration behind it.
