Filip Bajon obtained a degree in law in 1970. Before submitting his thesis, he started course in directing at the National Film, Television and Theatre School (PWSFTviT) in Łódź. In 1971 he published the novel Białe niedźwiedzie nie lubią słonecznej pogody (editor's translation: Polar Bears do not like sunny weather). Subsequent publications include the short stories Proszę ze mną na górę (Come Upstairs with me, 1979), and novels Serial pod tytułem (A Series Entitled) and Podsłuch (Taped, 1994). He completed the directing course in 1974. His graduation project was Sadze (Soot) from 1973, a story of a hero forced to suppress a workers protest in December 1970 but failed.
He took his first career steps after leaving film school at the Tor Film Studio, initially making short and medium-length documentaries and feature films. He sporadically directed documentaries as well as television theatre productions and stage plays. He headed the now-defunct Dom Film Studio for a few years.
Filip Bajon's first full-length film was Aria dla atlety (Aria for an Athlete). The director's style was surprisingly different and fresh compared to the slightly journalistic trend of the cinema of moral anxiety that dominated in the Polish cinema at the time. Some critics tried to present Bajon's work as an opposite creative trend. In an interview granted to M. Kornatowska, the director himself admitted that he saw a conflict in cinema between pragmatic immediacy and aesthetics. He said, "In cinema I am fascinated with creating the world from scratch, inventing it, in other words - a demiurgic function. All this, of course, can be brought under the notion of creativity". The formal means used in Aria for an Athlete were characterised expressively by cinematographer Jerzy Zieliński, who said that his task during the making of the film was to visually enrich each scene from the script. The instructions he followed could be summarised in the words extreme in every scene. The director also used this expression in a long interview (Szczun, W. Braniecki, 1998), saying he believed "a film has to be blown up, it has to show a world that never existed", and to achieve this "you have to show extreme situations". These words can be treated as his artistic credo.
Bajon even created a world that never existed in biographical pictures. A. Kołodyński wrote in 1980 that in the case of Bajon's films, a biography is only "the starting point for the vivid imagination", noticing a resemblance to the style of Russell and Fellini. In Fellini's case, this even involved quotes from his films, testifying to a fascination with the Italian filmmaker's work. Others (Lewandowski, Kałużynski and Gorzański) also noticed this, and the label "the Fellini from Poznań" stuck to Bajon, though some used it with tongue in cheek.
Building his film shots, Bajon also turned to visual arts (e.g. Aria for an Athlete features shots stylised to look like Toulouse-Lautrec's paintings and Beardsley's drawings). Kolodynski found that Bajon's film language contained "youthful intoxication with the art of the cinema spectacle, which sponges off painting, theatre and the reality of other people's lives, but uses this to build a world we yearn for".
Wizja lokalna 1901 (Inspection of the Crime Scene 1901) marked the start of a new perception of the director's work. The critics appreciated the film's visual value, but another important element was the treatment of a patriotic theme with cool rationalism, showing the school strikes against the Germanisation of Polish children in a way that was devoid of emotion. This did not preclude image creativity, and the combination of these two seemingly contradictory styles of speaking was a great value of the film. This picture and subsequent ones provided a basis for defining the topics on which the director focused. J. Lewandowski wrote, "Bajon is not interested in the mechanisms or tragedies of history, but in unique breakthrough moments that he presents as unusual visions of the end of the world", pointing out that in almost every film, and in his prose as well, Bajon is interested in the moment when "one era gives way to another", creating a "model situation of disintegration in which one can sense a mood of decadence".
It is hard not to agree with this, as in a way, the end of a stable world is portrayed in Aria for an Athlete, Inspection of the Crime Scene 1901, Limuzyna Daimler-Benz (The Consul), but also - now seen in a different context - an earlier film mentioned by the critic, Zielona Ziemia (Green Land), set at the turn of the 19th and 20th centuries. The director also touched on the theme of breakthrough moments in later films, to mention Magnat (The Magnate) and Lepiej być piekną i bogatą (It is Better to be Beautiful and Rich), and in a sense also in Poznań 56 and Przedwiośnie (The Spring to Come).
Filip Bajon has directed more modest films, such as Wahadelko (Shilly-Shally), Sauna, and Engagement, in which he used means more akin to television theatre. There is no question, though, that each time the ascetic quality of these pictures was the result of economic or political necessity.
