If I had one piece of advice for Rishi Sunak about delivering speeches, it would be this: “watch out what you stand in front of”. In this case, he stood in front of a uniformly blue background, which made for a wonderful green screen (even though it was actually blue in this case).
Stripping out the background was trivial
After stripping out the existing background and leaving a transparency, adding an alternative was the natural next step. I therefore present to you my masterpiece:
Rishi Sunak giving his speech from Scrooge McDuck’s vault.
