Since all the characters in Anthropoid were real people, it was possible to look up what happened to some of them.
Karel Curda, the snitch, was given a new identity, “Karl Jerhot”, and 1,000,000 Reichsmarks for turning in his friends. He married a German woman and spent the rest of the war as a Gestapo collaborator.
However, following the war, he was found guilty of treason and hanged on 29 April 1947.
ATA was killed along with all his family.
Not sure what happened to Marie.
