Man of Iron (Polish: Człowiek z żelaza) is a 1981 film directed by Andrzej Wajda. It depicts the Solidarity labour movement and its first success in persuading the Polish government to recognize the workers' right to an independent union.
The film continues the story of Maciej Tomczyk, the son of Mateusz Birkut, the protagonist of Wajda's earlier film, Man of Marble. Here, Maciej is a young worker involved in the anti-Communist labour movement, described as "the man who started the Gdańsk Shipyard strike", and a journalist working for the Communist regime's radio station, who is given a task of slandering Maciej. The young man is clearly intended as a parallel to Lech Wałęsa (who appears as himself in the movie).
Man of Iron clarifies the ending of Man of Marble, which left the death of Mateusz Birkut ambiguous. Man of Iron explicitly states that Mateusz was killed in clashes at the shipyards in 1970.
