Adam Sandler, Anderson Cooper, Jon Stewart and Jimmy Fallon were among those who made surprise appearances on Monday's episode after CBS announced that the late-night show would be ending in May 2026.

John Oliver, Stephen Colbert's fellow "Daily Show" alum, is speaking out about CBS' shock cancellation of "The Late Show."

When it was announced in 2014 that Stephen Colbert would succeed David Letterman as host of the CBS “Late Show,” reaction was mixed. Letterman, who retired after helming the talk show for 22 years, had a loyal audience.

Oliver has appeared multiple times on The Late Show with Stephen Colbert as well as the earlier iteration with David Letterman in 2015.

Joaquin Phoenix says he regrets his infamous interview with David Letterman, in which he remained in character for the entire, awkward conversation.
