It's only been a few weeks since Warner Bros. made that earth-shattering announcement at Comic-Con 2013 that Batman and Superman will square off in Man of Steel 2. It has long been known that Christian Bale has no interest in returning as Batman after The Dark Knight Rises ended his trilogy last year, but, according to a new e-book, that may not be the case.

The publishers of Beyond Batman: The Unauthorized True Story of Christian Bale and His Dark Knight Dilemma, which debuted this week, alleges that Warner Bros. has offered the actor a whopping $50 million to come back as The Dark Knight for Justice League, which is currently in development and will likely come after Man of Steel 2.

It isn't known if the alleged offer would include the actor returning in Man of Steel 2 or not.

Here's the official description of this e-book written by Vince Russell, which is currently available on Amazon.

""Beyond Batman" is the unauthorized true story of Christian Bale and his real life Dark Knight dilemma.

As the bat signal still glimmers with fervor above Bale's Hollywood marquee, this compelling, first-of-its-kind work recounts Christian Bale's inescapable experience as the Batman of our generation.

With three of the most successful Batman films in Hollywood history under his belt, Christian Bale is now facing extraordinary pressure to become The Dark Knight once more in the forthcoming Justice League film.

This compelling read exposes how sources close to Christian Bale have reportedly begun expressing their suspicions that Bale now views the Batman films in the same light that Robert Downey Jr. views the Iron Man films.

Although Downey has appeared as Tony Stark in four movies in less than a decade, he's hardly typecast as Iron Man. Downey has balanced his action film escapades with other projects that have harnessed his talents and earned critical acclaim in the process.

If Bale follows a similar formula, his box office glory days may not be behind him - a reality that other men who have donned the black cape weren't so fortunate to experience.

In the end, Christian Bale's future success as a top Hollywood draw may need Batman every bit as much as the Batman franchise still needs Christian Bale."

In related news, which seems to contradict the claims made in this book, The Expendables 2 star Scott Adkins has auditioned for the Batman role in Man of Steel 2. One would think that, if this huge offer was actually made to Christian Bale, Warner Bros. and Legendary wouldn't be auditioning other actors to play Batman in Man of Steel 2 and/or Justice League, especially since we reported just last month that Christian Bale is not coming back as Batman for Justice League.

We also reported in June that Man of Steel 2 will directly tie in to Justice League, meaning both movies would presumably feature the same actor playing The Dark Knight.

Stay tuned for more details as soon as more information is released.
