Speaking on U.K. breakfast television, the actress revealed that Clooney attempts to land a smacker on Smith.

"There's a very brilliant moment with Maggie and George — I don't know if I want to give away any more than that really — but George wants a kiss, and Maggie ends up on the floor. It's wonderful," she told ITV's This Morning.

Carmichael, who plays Lady Edith, also admitted that the cast had no idea that Clooney would appear.

"We didn't know it would happen until he turned up. We were filming anyway," she said.

The fifth season of the hit series debuted on U.K. broadcaster ITV on Sunday. The premiere drew an average audience of 8.4 million, the show's lowest season debut since its launch in 2010.
