Check out what he said:
"[Depp] was interested in doing the Jackie Boy character that Benicio [Del Toro] played [in the first one], but he was doing that movie 'Libertine' in Europe and it just kept getting pushed and delayed and went right through our shooting schedule," Rodriquez said of the actor he directed in Once Upon a Time in Mexico. "But there is a better role for him in ['Hell and Back']. I kept going, 'Gosh, Jackie Boy is a small part, he could be really good [as Wallace].' When he wasn't available, I thought maybe it was meant to be."
The director also mentioned casting Antonio Banderas:
"When I showed him the first sample of the work, he went, 'Man I'll do anything in that. I'll be the hunchback. You have to bring me onboard, that looks amazing,' " Rodriguez recalled. "So Frank met him that time too and he said, 'I have got to find something for that guy. I've never met him before. He's amazing.' [So we're] looking at the cast of characters and [looking] to see where he can fit."
