Celebrities reveal their real names | Reese Witherspoon, Meghan Markle, Lady Gaga and more

The Office star Rainn Wilson already had quite an unusual name to begin with.

But the 56-year-old actor has committed to changing it to something even more unique in the name of climate change.

Wilson announced he would be replacing his original name with Rainnfall Heat Wave Extreme Winter Wilson in a bid to draw more attention to global warming and protest the changing climate.

The comedian announced this bizarre name change on Twitter, revealing he had switched his moniker on all social media and his own “fancy writing paper”, which now reads: “Acid Rainn Kills Trees Wilson”.

While it isn’t an official legal name change, Wilson said he did it as a “cheap stunt to save planet earth”.

He couldn’t, however, change his name on Twitter because of Elon Musk’s crackdown on impersonation.

“Arctic is melting at Millions of Litres per second, yet this problem can’t seem to make a name for itself, so we’ll make a name for it,” he said.

“This is not a joke,” he also said in a statement to The Hollywood Reporter.

“I’m as serious as the melting Arctic, which amplifies global risks including extreme weather events around the globe.”
