Roger Ebert:..".. after the leviathan length of the Superman the Golden Age movies... on average 9-13 hours long.. each... they're toning down the movie-length drastically.. very, VERY drastically.. for the Superman the Silver Age movies.. which may all be only approximately.. only.. four hours long - each..?.. maybe even.. on a rare occasion.. only a three hour Silver Age movie.. only a three hour Superman Silver Age movie.. - once in a blue moon..?.."...
