Chuck Jones created a different kind of character in this 1953 Merrie Melodies short.
"From A To Z-Z-Z-Z" was inspired by James Thurber's The Secret Life of Walter Mitty, which had been adapted as a feature film starring Danny Kaye, and is being remade for release down the line with Ben Stiller. Ralph Phillips (Dick Beals, uncredited) is a grade school daydreamer whose fantasies include being a prize fighter and General MacArthur. Phillips would return in a sequel about a year later.
This short is dedicated to the memory of Dick Beals, who passed away on Tuesday at 85. Rest in peace, Dick.
