It really does say something about Graham Norton's likeability and the show's success that they've managed to have some of the most well-known personalities on the red couch. From screen legends like Harrison Ford to Katy Perry and Rihanna have all featured over the show's incredible run. Here's our ten favourite moments from Graham Norton...
10. KATY PERRY LET IT SLIP SHE SECRETLY MARRIED RUSSELL BRAND
Ah, those were the days. Katy Perry and Russell Brand. But, sure enough, it didn't last. But here she is talking about what it's like living with him and then it just sort of pops out. The fact she married him, not anything else.
9. ROBIN WILLIAMS BEING ROBIN WILLIAMS, BASICALLY
No joke, Robin Williams is hilarious. Not only is he a brilliant comedian, he's also got amazing improv skills. Just look at this.
8. WILL FERRELL DOING A PITCH-PERFECT HARRISON FORD IMPRESSION
If you closed your eyes, it actually sounded like him. And if you squint, he kinda looks him. Squint harder.
7. DANIEL RADCLIFFE SINGS THE ENTIRE ELEMENTAL TABLE
This is legitimately impressive. Ten points for Gryffindor.
6. HENRY CAVILL AND RUSSELL CROWE TALK ABOUT THE FIRST TIME THEY MET
It's hard to imagine Henry Cavill being fat. Not only that, Russell Crowe talks about the first time they met sixteen years ago when Cavill was playing rugby in school.
5. BENEDICT CUMBERBATCH FREAKS OUT HARRISON FORD WITH HIS CHEWBACCA IMPRESSION
Harrison Ford looks high as shit. Also, that's a really good impression.
4. JONAH HILL TALKS ABOUT THE ORGY SCENE IN 'WOLF OF WALL STREET'
Well, this needs no introduction.
3. MICHAEL FASSBENDER, HUGH JACKMAN AND JAMES McAVOY DANCE TO 'BLURRED LINES'
Again, no introduction needed.
2. PALOMA FAITH SPRAWLS HERSELF ACROSS MATT DAMON, BILL MURRAY AND HUGH BONNEVILLE
Also, Bill Murray totally tried to cop a feel of Paloma Faith. That happened and we all saw it.
1. WILL SMITH, JADEN SMITH, DJ JAZZY JEFF AND ALFONSO RIBERIO RELIVES THE NINETIES
Just goes to show that Alfonso Riberio still has the Carlton Dance down pat. Good for him.
