"...Uncle Vanea, a role in which Dellakeza reaches the state of grace of the performer-creator, a rare moment, if not unique in the actor's career. Humble lover or furious avenger, cabotin or ironic philosopher, drunk or lucid, Valer Dellakeza embodies a Vanea as some of us imagined him, maybe as Chekhov wanted him, certainly as Cornișteanu thought."

"Serving exclusively the Craiova National stage for more than 30 years, Valer Dellakeza finally had the chance of essential meetings, with important directors and first-rate roles, able to consecrate him as one of the great actors of his generation. "

"For this role, Castellucci organized an international casting that Valer Dellakeza (National Theater "Marin Sorescu" Craiova) won at the age of 81. An actor whose experience flourishes in speaking the text in Romanian (according to the director's concept, the word counts as vibration, as transmitted vital energy, not as semantic meanings), plus some quotes in Latin ("You can't tell the past what to do" , "Celebrating the edges keeps the circle intact", "The part that appears is nothing without the part that does not appear", etc.). Clothed in white, with a wooden staff for support, Jeremiah prophesies through verb and corporeality. Dellakeza is…divine!”

"... but there are also awards that can bury when they are too heavy for the shoulders that carry them. The past management of Boroghină (offff!), through the great performances of Silviu Purcărete, stood, after the departure of the two, like a sword over our heads, that's why we made a big, serious mistake. We lacked the mirror in which to believe. And to remind you, I and my theater are the recipients of the awards. Since the revolution, we have won 12 international awards at the biggest Theater Festivals in the world, and over 100 national awards."
