When David Letterman’s The Late Show returns to regular programming tonight with its writers in tow, the first guest in the post-strike era will be Robin Williams. Industry observers had questioned the caliber of guests that talk shows would receive, and it was believed that Donald Trump would be Letterman’s first guest. But the Screen Actors Guild said it supported the appearance of its members on shows like Letterman’s after the Writers Guild of America approved of the strike stoppage for Worldwide Pants writers, the production company for The Late Show and The Late Late Show with Craig Ferguson.

Jay Leno’s The Tonight Show also returns tonight with Republican presidential candidate Mike Huckabee as the first guest.

Conan O’Brien of Late Night and Jimmy Kimmel of Jimmy Kimmel Live, both ABC shows, have not announced their guests for tonight.
