This was the 24th appearance of the event, which has been held at every Summer Olympics except 1896. Seven of the 12 finalists from the 2000 Games returned: gold medalist (and 1996 finalist) Szymon Ziółkowski of Poland, silver medalist Nicola Vizzoni of Italy, bronze medalist (and 1992 silver medalist and 1996 finalist) Igor Astapkovich of Belarus, fifth-place finisher (and 1996 finalist) Ilya Konovalov of Russia, eighth-place finisher Vladimír Maška of the Czech Republic, ninth-place finisher Koji Murofushi of Japan, and twelfth-place finisher Alexandros Papadimitriou of Greece. The last two World Champions were Ziółkowski (2001) and Ivan Tsikhan of Belarus (2003). Tikhon, 2002 European champion Adrián Annus of Hungary, and Murofushi (bronze medalist in the 2003 World Championship and who, in 2003, had the best throw of anyone since 1986—a mark that is still, in 2021, the fourth-best throw of all time) were the favorites.
