Christopher Nolan avoided CGI and used 7ft stuntmen to portray Laestrygonians in The Odyssey. The giant leader, King Antiphates, is portrayed by actor Josh Stewart, while Matt Damon’s stunt double is Devyn Dalton, who is just under 5ft.

Josh Stewart plays Antiphates, one of the soldiers under Odysseus' command. Antiphates is also the name of the king of the Laestrygones, who is not credited with that name in the film. Best I can tell with a cursory look on imdb, Stephen Adentan plays the main Laestrygonian.
