Favourite performers

Who is a performer that you would always see regardless of the quality/theme of the show?

Mine are:

Patsy Ferran, absolutely mesmerising in Summer and Smoke.

Sally Field, she walked on the stage and it was like everyone else disappeared (All My Sons)

And Gillian Anderson who in my opinion is a goddess!

Edit Wow some amazing names here - looks like I need to up my game with seeing shows! Thanks everyone
