Being on good terms with the regime, he made several films before 1990, including Lost Forest/Pădurea pierdută (1972), The White Darkness/Întunericul alb (1982), The Moment of Truth/Momentuil adevărului (1989) and Wrath/Urgia (1976, co-directed together with Iosif Demian).
After 1989 his career declined in terms of quality, and he dedicated himself to film teaching. He also directed the features Divorţ din dragoste (1991), Crucea de piatră (1993) and Terente - regele bălţilor (1995). Alone versus Myself/Dulcea saună a morţii (2003) was his last film.
He was co-founder of the Film Faculty from Universitatea Media (www.universitateamedia.ro), which is part of MediaPro portfolio, and was its Honorary Dean upon his death. During his career, Blaier was awarded several times by the Romanian Filmmakers Association.
