In particular, Forman, Ivan Passer and Jaroslav Papoušek have collectively become known as the "Forman school" of filmmaking, which combines an interest in documentary realism, including consistent focus on the quotidian, with a surrealistic tendency to "uncover the hidden side of reality, its comical or monstrous quality which lies just beneath everyday mishaps, stutters and waverings". Diane Sippl has noted that, once Forman came to America and created his high-profile Hollywood productions, such as "One Flew Over the Cuckoo's Nest", "Hair" and "Amadeus", he was able to introduce into commercial cinema the same qualities that characterized his early films like "Loves of a Blonde": "An acute observation of the ironic details of mundane life; an intimate understanding of emotions, both projected and silenced; a keen sensitivity to the moment when solemnity melts into farce,"
