Lois Lane also has an important role to play as she investigates Luthor's suspicious business dealings, and Bruce Wayne is the business rival of LuthorCorp. So there are many interesting dynamics between the characters, and similar dynamics might play out in the film.
What makes the novel unique, however, is that it is set in the Cold War era and the Russians play an important part in the plot, as does the nuclear arms race and the mania around UFOs. Also, Superman and Batman are both portrayed in a very stereotypical manner -- not that that's a bad thing -- and we get to see Anderson's take on the traditional Lois Lane / Superman rescue-meeting and the Lane-Superman interview. There's also an interview between Clark Kent and Bruce Wayne.
