Joss Whedon was airlifted in to fix Thor: The Dark World
By Sean O'Neal September 18, 2013
Whereas normal people are forced to slog through their days just accepting the stilted dialogue and strained exposition, director Alan Taylor has at his disposal the Marvel studio machine—and thus its most valuable resource, Joss Whedon. Speaking to SFX Magazine, Taylor discussed how a couple of problems on Thor: The Dark World led to him calling in the big, quippy guns, whereupon Whedon “basically got airlifted in, like a SWAT team or something” out of a scene that Taylor couldn’t make exciting to save his life. Instead Whedon did that for him, rewriting the script on the spot and—after Taylor says he grabbed Whedon before he could get back to his plane—playing fixer on two more scenes he was having trouble with, presumably just nonchalantly tossing the edits over his shoulder as he swaggered down the jetway.
According to Taylor, those Whedoned scenes were “were just much better and much lighter on their feet… much more fun, much more surprising than what we had been trying to do,” which is definitely what you airlift Joss Whedon in for, if you can afford it. Hopefully Whedon will soon get to the point where he can devote himself to philanthropically flying around the world visiting the less fortunate, swooping in like a guardian angel to punch up their lives a little.
