An origin story certainly falls into that broad category, although that same report said the movie wouldn’t show how Wonka rose from adversity and developed his fondness for sugary sweets…or something along those lines.
When the first report broke out about Warner Bros tackling a younger Willy Wonka, it was described as a standalone tale focused on his “early adventures.”
That said, this revelation conflicts with what we previously learned about the project.
Given that Simon Rich (who wrote The Secret Life of Pets) is early into the drafting process, it may be a while until he and the other creative minds iron out the story details.
