Bullshit, Cher has a Oscar, Paltrow has an Oscar, Cuba Gooding Jr has a Oscar, even Frank Sinatra (honorary in the 1940's, and best supporting in the 50's) has a couple of Oscars..... An Oscar is just a sign that they had one good performance.
Mark Rylance, bit part actor for thye most but always delivershttps://www.imdb.com/name/nm0753314/Great movie
JeezWinning just one Oscar now means your not necessarily a good actor
