YOUR 10 or 5 greatest Actors of any given era

I was perusing the interwebs and found several 100 greatest actors of all time lists, and I couldn't find Danny Kaye in none of t hem. Do tell me your 5 or 10 greatest performers of all time in increments of 10 years. Beginning in 1920. If you cant come up with 5, even 3 is enough.1920,1930,1940,1950,1960 and so on You dont have to mention every era of course. A few actors that are burnt into your mind or heart is enough. Mine of all time is Danny Kaye
