His jovial figure made Brezeanu ideal for comedic roles, above all in the works of Ion Luca Caragiale, whose favorite he was.
[1] From 1906, at the request of Alexandru Davila, he played the tragic figure of Ion in Caragiale's Năpasta.
In all, Brezeanu interpreted nearly 200 roles, including Mogâldici from Viforul and Luceafărul by Barbu Ștefănescu Delavrancea (1909, 1910), the Fool in William Shakespeare’s King Lear (1910) and Șbilț from Mihail Sorbul’s Patima roșie (1916).
In 1924, his Shylock, in Shakespeare’s Merchant of Venice, drew favorable comparisons to Ermete Novelli‘s portrayal.
He also played Harpagon in The Miser by Molière and the Mayor in The Government Inspector by Nikolai Gogol, the latter evoking a favorable review in 1909 from N. D.
