If Sonny can't help, you must look for an archery coach in the Chicago area. If the actor has no experience with bows you must start with a lower draw weight. With a higher weight he will fight with the bow and this won't look cool in the movie. Usually actors are in very good physical form, but archery requires training of specific muscles. An archery coach will teach him a proper archery form which is needed for accurate shooting but it also looks good. Good luck and if you have any questions we'd do our best to help. We all will be glad to help in making bowshooting even more popular.
