Answer: I did an Internet search for this quote, including checking best-quotations.com, and the only reference of it I can find is tied to the movie. I do not think this is an Oscar Wilde quote. If I find something, I'll update this, as it's possibly a line from one of his plays or novels that just doesn't happen to be online. Someone else might know.
