If you see at real 8w9 Sp/Sx like Clint Eastwood, Jack Bauer, Lincoln Burrows, Robert de Niro, Paul Newman or Sigourney Weaver you'll see that they are serious, tough, reserved, have nothing juvenile in them and look bigger than they are. They are strong, tough, and that can be consider as similar with Mila Kunis's counterphobic 6bravado, she's someone who act without care about rules and damn the consequences. But she's very bubbly, energetic and nervous, she leads from the head and have not that imposing physical presence that even females 8w9s have.
On this interview of Robert de Niro, you can see how different they are, see also about Angelina Jolie who is almost of the same type than Mila Kunis being an ESTP 6w7 Sx/Sp. See how similar they are and compare also with other females 6w7 like Amy Winehouse or Avril Lavigne, and you'll see the similarities in term of global stance, attitude and mannerism.

Of course, I talk about counterphobic females 6w7, Calista Flockart, in comparaison, is a phobic 6w7 Sp/Sx (and she's INFJ!). Completely different, but you still can see a sort of "point".
