If I were Kenneth Branagh, I'd be a bit dissatisfied as having myself only mentioned as ''the director of THOR.'' (And HENRY V, DEAD AGAIN, MARY SHELLEY'S FRANKENSTEIN and SLEUTH, thank you very much.)
I get what you're saying, however, this films target audience isn't going to be familiar with his prior work. IMO the target audience is "action film fan who saw MI:4, Bourne 4 or Skyfall", is 15-30yrs olf, not necessarily the Clancy readership which likely skews a larger age range demo
Thor is recent and did well so it makes sense to relate them together.
"You liked Thor a couple years ago, try this, same guy"
