Joker: 10 1970s Comic Book Movies DC Should Make Next

Sticking with Pakula, his most enduring and most iconically 1970s movie All The President's Men would also be perfect for a Joker-style reimagining of DC heroes.

One of the many problems faced by Zack Snyder and his team in adapting Superman for the modern DC Extended Universe came in how to incorporate his regular job at the Daily Planet. Print media is increasingly irrelevant in the current age and, while Lois was given a sort of investigative journalist plot thread after the massacre in Africa in Batman v Superman, but it felt tacked onto the movie's wider plot.

All The President's Men's story of Washington Post journalists Woodward and Bernstein's investigation into the Watergate scandal, however, takes us back to the days when journalists could be seen as relevant heroes and newspapers really mattered, were widely read and people still hoped that they would print the truth and hold government and businesses accountable.

This could be the perfect grounding for a relatively realistic take on the Superman mythos that takes Clark Kent seriously as a character first and foremost, not the guy in tights and a cape.

A story in which business mogul-turned-president Lex Luthor's dirty secrets are uncovered by the investigations of a smart pair of crusading journalists - Lane and Kent - would also, like Joker, serve to use the iconic comic book characters and period setting to nevertheless make a pertinent comment on the politics of today.

And, if Supes has to suit up in the final act to take Lex down, at least there's ample evidence that he tried to do things the legal way first.
