“Justice League” opens with Batman in full "Caped Crusader" mode as he catches a notorious criminal, played by “Mindhunter” star Holt McCallany. It's all fairly standard and played pretty seriously, but according to McCallany, it originally had the dry humor that Whedon is well known for.
“I love Joss Whedon. My scene with Batman was originally conceived as a comedic scene. That’s how Joss wrote it, and that’s how we shot it,” he told Men’s Fitness (via Collider). “I thought it came out great, but the studio felt it would be a mistake to open the film with a completely comedic scene, so it was re-edited a little bit. I was disappointed, but when I got home to New York I found a bottle of my favorite champagne and a note from Joss that said ‘To Battles Lost. Gratefully, Joss.’ I can’t tell you how much it meant to me that he took the time to write to me. Joss Whedon is a class act. I had the letter framed.”
With people pressuring the WB to release Zack Snyder's cut of the film, why not have a double set with both Snyder and Whedon's versions included? It would surely be a popular seller and we could decide ourselves which version was better.
Martel has only made a handful of features in 25 years ("La Ciénaga," "The Holy Girl," "The Headless Woman," "Zama"), and every one of them has been an event for festival audiences.
