Listen to his recent EMPIRE podcast interview recorded in front of a live audience where he talks about his latest film, the movie business, stunt work, etc. His English is fine and actually adorable (and he talks so fast, which isn't easy to do in a foreign language!), he even admits his English used to be worse in the past when he first got started and that it's still not very good, but that's just Jackie being insecure, like someone else had already pointed out. Everyone in the audience LOVED him, as did the podcasters.

Like Jackie said once: "Everyone adore me." :D
