Here's a pointless parlour game for animation fans: what's your choice as the best team of animators ever assembled for a short cartoon?
This is distinct from the question of what cartoon had the best animation (though it overlaps, of course; you wouldn't pick a cartoon with four once-great animators past their best). The question is more akin to those baseball questions about what was the greates infield of all time; what cartoon assembled the best group of "players" at the peak of their skills?
Mine is a very conventional choice, but I think it's hard to beat the team assembled for Bob Clampett's Looney Tunes short "Book Revue." The credited animators were Robert McKimson, Rod Scribner, Manny Gould and Bill Melendez. That's four truly great and unique animators, each one in his prime. Also if you want to take into account the overall career achievements of the animators (sort of like taking into account the "career value" of infielders), two of the four went on to important careers as directors, McKimson and Melendez.
Oddly enough, though all four of those guys were associated with the Clampett unit, this is one of the few cartoons (perhaps the only one?) where all four of them worked together, because McKimson was promoted to director almost immediately after Melendez re-joined Warner Brothers, and when Melendez was working for WB earlier, Gould wasn't there yet.
