Corporations can only donate on your behalf, so they get no tax benefits whatsoever. They cannot claim the money you donated as income nor can they donate it under their own name. The only thing they can do is use it for PR and tell the public “they helped raise $x for this cause”.
That said, if you donate a non trivial amount to charity, you should do it directly with the charity so you can get a tax receipt and write it off on your personal taxes.
I’ll talk all kinds of shit about that movie, but I’ve watched it end to end more times than most movies I’ve seen, and it’s never been a hate watch.
