All actors wear makeup. And not just actors. One thing that I really hate and cannot stand seeing is men with shaved eyebrows.
I recall many years ago I was on stage in Leeds and after the dress rehearsal I was famished so straight off to the Pizza take away in Harrogate Road (just opposite the Zermatts) to get some sustenance. The only thing was I was still in costume - as a clergyman (cassock and clerical collar) and still had stage makeup on! Close up it looks grotesque and I still think about the sudden quiet that greeted me on my arrival. It was less enlightened times - about 1981 or 1982 if I recall correctly.
The play was one where I was really a police inspector disguised as a priest to trap the suspects! I seem to recall it was one of the few I did where I really knew my lines!
