The always excellent Star Wars Always posted a quote form Benicio del Toro in which he confirms he is in talks for a Star Wars: Episode VIII role with director Rian Johnson:
I can’t tell you much about it but I think that it might happen. It looks like it’s gonna happen so I’m very excited… I can’t talk too much about it. The script is hard to get. They told me they’d cut my finger if I talk about it… I saw the original one when it came out and it marked me. I was impressed by the film and by the characters and by the story and the message.
It is strange for the actor to be so forthcoming about a film he’s in talks for. I do hope he gets it. I think he has a lot of offer the Star Wars galaxy. It should be no mystery that some villains in The Force Awakens will have to die and he would make a great replacement in my estimation. This confirms an earlier report he was up for a role.
