If this was a real movie how would it be funded?

If this was a real movie how would it be funded? Our movie would be able to be funded by the studio producing our movie and the distribution company. These companies would fund our movie and give us an amount if they like the idea and think the movie will make a profit. We could also be funded by sponsors who will advertise their product in the movie. For example, using apple products in the movie and apple pay to be in the movie. Our movie could be sponsored by any company but mostly by companies or items with the same target market and theme. In our movie we have used products like OREOS and iPhone so if the movie was real we would be sponsored by them.
