He was Minister of Culture between 1996 and 2000, in the Romanian Democratic Convention (CDR) cabinets of Victor Ciorbea, Gavril Dejeu, Radu Vasile, Alexandru Athanasiu, and Mugur Isărescu.
Caramitru was a protagonist in a series of theatrical productions by directors such as Liviu Ciulei, Moni Ghelerter, Andrei Șerban, Silviu Purcărete, Sanda Manu, Cătălina Buzoianu, Alexandru Tocilescu, and Sică Alexandrescu (acting in plays such as Mihail Sebastian's Steaua fără nume, Georg Büchner's Danton's Death, Aeschylus' The Oresteia, Tennessee Williams's A Streetcar Named Desire, Carlo Goldoni's Il bugiardo, and in many of Shakespeare's works).
As a director of theater, opera, and operetta productions, Caramitru notably staged works by Frederick Loewe (My Fair Lady), Marin Sorescu (The Third Stake), Benjamin Britten (The Little Sweep), Aleksei Nikolaevich Arbuzov (The Lie), and Shakespeare (The Merchant of Venice); his adaptations of Peter Brook's La Tragédie de Carmen and Pyotr Ilyich Tchaikovsky's Eugene Onegin were hosted by the Grand Opera House in Belfast, Northern Ireland.
Later in life, Caramitru has had minor roles in foreign films: he was an anarchist in the 1991 Kafka, Tatevsky in Citizen X (1995), Zozimov in Mission: Impossible (1996), Count Fontana in Amen.
On 22 December 1989, after President Nicolae Ceaușescu had fled Bucharest, Caramitru and the known dissident writer Mircea Dinescu joined the crowd occupying the Romanian Television building, and were prominent among the numerous speakers who were proclaiming revolutionary victory.
[12] According to Alex Mihai Stoenescu's research, despite its passing into contemporary folklore, such a phrase was never uttered; instead, the words used were "Mircea, arăți că lucrezi" ("Mircea, show that you are working on something" — while holding Dinescu's booklet in front of camera), to which Dinescu replied "La un apel" ("[I'm working] on an appeal [to the people]") — pointing rather to their ill-preparedness and their preoccupation in quickly drafting a proper document.
[14] Already a member of the Civic Alliance Foundation, he joined the National Peasants' Party, which engaged in opposition to the FSN, and became Minister of Culture after the CDR coalition won the elections of 1996.
