...that a playwright can win? (I.e., is it considered more prestigious than a Tony Award?). I always thought so but I don't know if my perception is correct.
"You can't overrate Bernadette Peters. She is such a genius. There's a moment in "Too Many Mornings" and Bernadette doing 'I wore green the last time' - It's a voice that is just already given up - it is so sorrowful. Tragic. You can see from that moment the show is going to be headed into such dark territory and it hinges on this tiny throwaway moment of the voice." - Ben Brantley (2022)
"Bernadette's whole, stunning performance [as Rose in Gypsy] galvanized the actors capable of letting loose with her. Bernadette's Rose did take its rightful place, but too late, and unseen by too many who should have seen it" Arthur Laurents (2009)
"Sondheim's own favorite star performances? [Bernadette] Peters in ''Sunday in the Park,'' Lansbury in ''Sweeney Todd'' and ''obviously, Ethel was thrilling in 'Gypsy.'' Nytimes, 2000
Playwrights and composers definitely dream of winning a Pulitzer if they're American... if only be on the same list as Tennessee Williams, Edward Albee, Stephen Sondheim, Jonathan Larson, August WIlson, Aaron Copland, Richard Rodgers, etc...
I would say, yes, it is the most prestigious because it's only for the playwright's work, since it's a writing award, whereas the Tony is for the entire production, not just the writing.
