Earlier in the day, Bradley promoted the flick during an appearance on The Tonight Show with Jay Leno in Burbank.

“That was simply a scheduling thing. And I think it was important to make a statement because I just wanted to make sure that there wasn’t any bad — they’ve already changed directors, you know, you don’t want it to seem like it’s a cursed project,” Bradley recently shared about his exit from the upcoming film Jane Got a Gun.
