Mickey's Polo Game Anecdote
"Dave Hand kept urging Walt Disney to let them do a WHOLE film in ruff. Walt was reluctant but when Dave was preparing "Mickey's Polo Game," Walt was traveling and Dave had all of Polo Game ruffed without informing him.
Disney saw Polo Game finished in colour and gave his OK. Only then did Hand show him the complete linetest in ruffs and Walt's reluctance evaporated."
(To me, this story shows that Hand must have had a BIG star in Walt's book, because Walt seems to not have been anyone you'd spring a surprise like this on, and keep your job. This wasn't long before Hand became Supervising Director of Snow White...)
