I've always thought that this was a fun film to watch. Kirk Douglas with his impressive physique is well cast but I think Ernest Borgnine steals the show playing his father. A great role for him. Maybe Tony Curtis looks a little out of place among the vikings but he's always been a good enough actor to pull it off. Great sets and just beautiful cinematography. The film was shot on real locations in Norway. If you get a chance to see this just sit back and enjoy this fun adventure film.
