There was a paper entitled "Fighting Films: The Everyday Tactics of World War II Soldiers" by William Friedman Fagelson in Cinema Journal vol. 40, no. 3. The abstract at the beginning states: "American soldiers watching movies near the front lines during World War II talked back to the screen, interacting with the texts and with each other." Hope this is a help. ---- Screen-L is sponsored by the Telecommunication & Film Dept., the University of Alabama: http://www.tcf.ua.edu
