The "Brundibár" footage from the film is included in the Emmy Award-winning documentary "Voices of the Children" directed by Zuzana Justman, a Terezin survivor, who sang in the chorus. Ela Weissberger, who played the part of the cat, appears in the film. The footage appears again in "As Seen Through These Eyes", a 2009 documentary directed by Hilary Helstein. There Weissberger describes the opera in some detail, noting that the only time that the children were permitted to remove their yellow stars was during a performance.
