‘Dark Knight’ Trilogy’s Christian Bale and Tom Hardy Had a Secret Code That You Never Noticed

Considering Hardy and Bale wore costumes that covered their faces and made talking difficult, it's not surprising to learn they created loopholes around them. After all, they're intelligent men!

The Dark Knight Rises was the final movie in the Batman trilogy starring Bale as the titular character. Bane (Hardy) joined the cast as the main villain alongside his master, Talia Al-Ghoul (Marion Cotillard), and her father.

Bale described the secret code as using finger prompters because they couldn't hear each other over the background noises and hindering face masks. So, once one person finished reading his lines, he'd flick a finger discreetly to cue the other into a response.

They performed so well that fans never noticed the finger prompts, and now, everyone is going back to watch those scenes and try to catch the finger prompts. It was an interesting improvisation that explains why directors and producers pay millions of dollars for certain actors and actresses.

Bale has since shed his black cloak for other iconic roles, including Michael Burry in The Big Short, Gorr the Butcher in Thor: Love and Thunder, and Ken Miles in Ford v. Ferrari. Last year, Bale also starred in the much-talked-about Amsterdam alongside Margot Robbie and John David Washington and The Pale Blue Eye, which comes to Netflix this weekend, January, 6.

The Pale Blue Eye is a mystery thriller set in the 1830s about a veteran detective, Augustus Landor (Bale), who investigates a murder with Edgar Allan Poe. Bale's revelation about his secret code with Hardy came during The Pale Blue Eye's movie promotion.

Bale described his role in The Pale Blue Eye as a realized dream because he'd always admired the late author Edgar Allan Poe (Harry Melling). He encountered the character through his father, an English teacher after the older Bale encouraged him to read the 2003 novel, The Pale Blue Eyes. 

Bale co-produced the movie with a $72 million budget but only cracked $129,928 at the Box Office within a day. The movie showed in limited American theaters during the holidays for a day before the company pulled it for Netflix.

The Pale Blue Eye has average ratings from critics but you can watch it if you're into 19th-century murder-mysteries and Bale at the center of the investigation.
