Wow! I have a copy of the JLA, too. What I really want is to get my hands on the 1970s version of the JLA cartoons. These may not be as good as the JLA series today but I did enjoy them as a kid.
As for Gung Ho, I've seen this movie once when my Dad rented it for his betamax machine several years ago. I think I might have enjoyed it but I only have a fuzzy recollection of the movie.
I just saw Victory in the Pacific on the National Geographic Channel the other night, then Bridge on the River Kwai last night and Battlestar Galactica (I think the last two episodes of Season II).
