If you’re a fan of Bradwell Institute, go ahead and circle March 18 on your calendar. That’s when “Welcome to the Jungle: The 2004 Bradwell Tigers Documentary” will make its world premiere at Liberty Cinema in Hinesville. The hour and 17-minute documentary is by former BI linebacker Chris Bell, a San Antonio filmmaker who has been working on the project since 2014 through his production company, Bell Filmz.
