3) The Reasons Superman Didn’t Detect The Bomb
Another gaping plot hole in the cinematic version of the movie is the question of why Superman did not see the bomb hidden in Walter Keefe’s chair, the one used to blow up the Senate. There is a line where Clark suggests to Lois that he didn’t want to see it, but that’s flimsy at best.
In the extended cut, however, this does get an adequate explanation. Jena Malone’s Jenet reveals to Lois that the chair was in fact lined with lead, meaning Supes could not see through it. Like the burnt bodies, this was another measure of Lex’s to ensure Superman looked guilty.
Superman also looks like more of a hero here, as he stays to help out the injured victims after the explosion. In the original film, he just flew off seemingly without a care for those in need.
