Groucho's present rating on TV will be a good send-off for a son's eye view of his father which if devoted is not always doting. The pattern, as well as the pater is familiar- the childhood and family background, the way up, the big time on Broadway, in pictures, -- as you follow Groucho and his well-known brothers through their madcap careers. The special touches are in the little details of family life as Father's inconsistencies about money swing from extravagance to miserliness; as his fiendish and unruly tongue and definite likes and dislikes finally alienate his first wife; as golf, travel, tennis and music take their place among his occupations and hobbies; as the crash in the '30's and a failure to keep his sponsors on radio slow up his confidence. A confusing guy for a father (who sidetracks the issue by appending footnotes to the text) but one who bears up well in this candid camera biography and whose talk is as fast off as well as on stage. Spry.
