The "Big Bad Wolf" and chickens?

[Joel S. Berson]

In his review of the movie "Last Lions" in the Boston Globe, Ty Burr
note that Jeremy Irons, its  narrator, once played "the villainous
uncle" in "The Lion King".  Burr writes, "this is a little like
hiring the Big Bad Wolf for a documentary about chicken farming."

Shouldn't that be "about hog farming"?  Or perhaps "pig housing"?

(And the analogy feels a bit off anyway, but I can't articulate why.)
