In anticipation of the short Downton Abbey film debuting later this year, a short clip reveals the latest high-profile guest to be stopping by to visit the Crawley family—Lord George Clooney.

The clip comes from the charity film set to debut during the holidays on the British network ITV. The clip doesn’t reveal who Clooney will be playing or why he’s there. Cora appears to mistake Clooney’s character for Lord Grantham, but everything else about him remains a mystery.
