 After Busby Berkeley (qv) finished directing the finale ("I Got  Rhythm" number, which was filmed first), he was fired by producer  Arthur Freed (qv) and replaced by Norman Taurog (qv). The  reasons vary: modern sources say he was way over budget and behind  schedule. Freed himself claimed it was because of a personality  clash with Judy Garland (I) (qv), who requested his dismissal.
