My story is the same as most of us here. I always stay to watch the entire
credits and started noticing Mo Henry's name. and finally checked it out on imdb
and then found this group. In my web searching I noticed this reference to Mo
in an article about restoring "Superman".

"anyway, I had all the cut negative sent over to Mo Henry, the Warner Brothers
negative cutter at Technicolor. The studio already had the film hand cleaned and
Mo inspected the original negative and had Technicolor repair any weak splices
or damaged perfs. There was a big chunk that was a dupe negative section, when
Lex Luthor pulls the Kryptonite out of the case all the way until he pushes
Superman into the pool. The original cut negative had been damaged by some lab,
and somewhere someone combined YCM separations to make the dupe section. The
colors were slightly out of registration. We never did find the negative for
that. There was a dupe section for all of that and then there was
damage in other places, torn frames, stuff like that which had been backed by
mylar They would put clear mylar on the back of the negative so that the tear
wouldn't pull any farther and it would hold the film together. "
