However, as the director points out, "Somehow it didn't."
"When Anthony Daniels (who plays C-3PO) told me, 'Oh my God, I love BB-8!'I said, 'We’re going to be OK,'" Abrams continued. "Because if he’s OK, it’s working."
"It’s a little bit like having a party and having friends from your new school meet friends from your old school, and you think, 'What’s going to happen?'" he added.
