I'm going to a celebrity fancy dress party on Saturday.  No celebrities have been invited to my knowledge.  It's a celebrity fancy dress party in that the guests have to dress up as a certain celebrity.

I haven't yet properly thought about who to go as.

I have a grey bushy fake beard.  Can anyone think of any celebrities with big grey beards?

Alternatively, can anyone think of any celebrities it would be easy to dress up as?

Thanks!
