In The Dark Knight Rises, when Selina Kyle (Catwoman) disappears from a rooftop, Batman's remark "So that's what that feels like" is lifted directly from the DC graphic novel "Kingdom Come". Even the circumstance is similar, except it was with Superman.
In Batman Begins, during the filming of the scene where Batman is being towed by a train through the streets of Gotham, so much steam was used that it would "rain" on the cast and crew for several minutes after each take.

In The Dark Knight Rises, in the football stadium sequence, the cast and extras are all wearing heavy winter clothing, though the scenes were shot during a massive heat wave across the East Coast during the summer of 2011.
