Digby, as the title claims, is a big ol' dog who was a cute little pup before he lapped up a compound meant to produce bigger vegetables. The gargantuan canine makes for the usual sight gags, culminating when Digby licks up a vast lake. Beaumont, the dog's owner, tries to locate a reducing
serum before the Army can blast his pup into oblivion. The film drags because too often, instead of Digby and his owner on the screen, there are some not-so-comic comics. Producer Shenson also delivered Beatle films HELP! and A HARD DAY'S NIGHT.
