I was watching this great show the other night and thought I had drifted off into a parallel universe. Ward Cleaver was not Hugh Beaumont (attached image is of the actor Casey Adams) and Wally was not Tony Dow - surreal - thought June Cleaver was cheating on Ward. Turns out the episode ("It's a Small World") was the pilot episode first televised April 23, 1957 on Studio '57 without a laugh track nor the series' well known theme song. Have to say, the actor changes was well warranted. Neither actor was as credible as Hugh and Tony. In this pilot, Diane Brewster appears as Miss Simms, a secretary, with Richard Deacon as Mr. Baxter, Miss Simms' boss. Brewster and Deacon would find roles in the series as Miss Canfield, Beaver's second grade teacher, and Fred Rutherford, Ward's co-worker.
