The OMGOMGOMG THE ACTORS ARE SO MUCH LIKE THEIR ROLE 😱😱😱 is part of marketing

But he really seems to be into it (and frankly speaking, actors should do a research for their roles and try stuff their characters are good at, well, to a reasonable extent, I don't really expect Henry Cavill try flying)

no, I'm thinking more about people like Meryl Streep, who learned Polish AND German for her role in Sophie's Choice or Viggo Mortensen who learned Russian and Russian gang culture to play a Russian mobster in Eastern Promises.
oh but it's everywhere!
