CRITICS’PICKS

It’s likely that more people have heard of Busby Berkeley than have seen his astonishing dance numbers in their entirety. Helping to change that is a 10-film retrospective put on by the UCLA Film & Television Archive starting Friday night at the Hammer Museum in Westwood. This is a welcome opportunity to see the eye-popping routines Berkeley created during a long career in Hollywood in the only kind of presentation -- a theatrical-size screen -- that do them justice. If you have time for only one double bill, Tuesday night’s pairing of the James Cagney-starring “Footlight Parade� with the Depression-themed “Gold Diggers of 1933� is the one to see.
