It’s been nearly nine months since he killed off ‘The Colbert Report’ to take over from David Letterman on CBS, but Stephen Colbert has now revealed some details about what ‘The Late Show’ will look like under his aegis. And boy, has he gone big, announcing that the star guest on his debut show will be Hollywood heavyweight George Clooney.

The major A-list actor will be the first person to chat with Colbert when he begins on September 8th. On Friday morning, the new host tweeted his followers: “George Clooney will be my first-ever #LSSC guest on September 8th! Could one of you let him know?”

Ocean’s Eleven and Tomorrowland star Clooney was, of course, one of David Letterman’s final guests before he signed off on May 20th this year having presented the show since 1993 from New York’s Ed Sullivan Theatre.

The new show with Colbert will complete a long period of transition for the network’s late night schedule. British star James Corden took over on ‘The Late Late Show’ in place of Craig Ferguson on March 23rd to positive reactions.

The unveiling comes less than a day after Colbert joined Jon Stewart on his last ever episode of ‘The Daily Show’ on Comedy Central, the show that helped launch his comedy career in the early noughties, whereupon he landed his own series on the same network, ‘The Colbert Report’, in 2005.

The 51 year old presenter also took the time to thank his old mentor on Friday morning on behalf of all the fellow ‘Daily Show’ alums that began their careers on the programme. “We owe you, because we learned from you.”
