  Dinulescu in "Uriel Acosta" by Karl Gutzkow		Dinulescu in "The Jewish King Lear"

Natalia Stancu, in "The Jewish Reality", 2012, states about D. in his performance in "The Jewish King Lear":

”The great chance of the performance is Constantin Dinulescu. An actor of great distinction and experience, who carries magisterially the hero’s deep feelings and complexity, through an acting of classical proof and exquisite modernity. His David has the importance of an affluent bourgeois and a mentsch. He has a patriarchal authority, which imposes respect. He doesn’t seem tyrannical or abusive. The hero’s effort to break his limits and prejudgments is impressive...(..) Here he is, living painfully the consequences of his drastic decisions Really exceptional are the moment when interchanges the heartbreaking revelations with auto irony and sarcasm, a way of commenting lucidly and histrionically about the absurdity about how the human being becomes a jester of destiny.”
