Now that Birdman has been named Best Picture of 2014, it’s time to dig into its imaginary past and present an award-winning short film “Busy Day for Birdman,” from 1967. This version is captioned for Hispanic viewers. It is introduced by Turner Classic Movies host Robert Osborne. It’s a prequel of sorts for the insanely popular “Harvey Birdman: Attorney at Law” series that appeared on Cartoon Network’s “Adult Swim” programming block.
