Andy Serkis is one of the world's most talented actors, even though you probably won't recognize his face. Serkis is the go-to guy for motion-capture performances, from "King Kong" to the "Planet of the Apes" reboots to his most renowned role as Gollum in the "Lord of the Rings" trilogy.
It was a given that Gollum would come up during Serkis' guest appearance, considering that Stephen Colbert is the biggest "LotR" fan in late night. In a delightful detour from talking about "War of the Planet of the Apes", Colbert asked Serkis to read a few of Donald Trump's tweets in character as Gollum. The results were...scarily appropriate. He even found Trump's own version of "my precious" (it's "sad!").
