I'm not remotely a fan of Chuck Jones, but this is one of his better efforts. The premise is intriguing: Daffy Duck (or one of his ancient ancestors) was alive 'trillions' of years ago, and crossed paths with a hungry caveman.
Casper Caveman has a pet apatosaurus named Fido, who is drawn and animated as one of Chuck Jones's usual insufferably twee critters. However, I laughed out loud when the dinosaur tags along behind his prehistoric master. Two-legged Casper and four-legged Fido each have a distinctive gait, and when they walk in unison the visual counterpoint of their movements is very funny.
For some reason, many Warners toons of this period begin with a multi-plane shot, apparently hoping to convince audiences that they can be just as 'arty' as Disney's cartoons. However, the very crude multi-plane pan near the beginning of this toon (more of a 'bi-plane'; only two planes!) is not remotely as impressive as Disney's multi-planes in 'The Old Mill' and elsewhere.
This cartoon violates the laws of physics even more than usual for Termite Terrace standards, with objects and characters able to pause in midair and change direction ditto.
Various sources have stated that the character Casper Caveman in this cartoon is a caricature of Jack Benny. Well, yes and no. The vocal performance (by Jack Lescoulie) expertly copies Benny's distinctive delivery and some of his catchphrases ('Good night, folks.'), and Jones's animation even duplicates a few of Benny's gestures. However, the character as drawn simply doesn't look like Benny, neither facially nor physically. I wonder if this was an attempt to avoid a lawsuit. Or perhaps it was down to the fact that Jack Benny (who had already made some film appearances dating back to the late 1920s) was at this point best known as a radio star, so movie audiences might not be sure of what he looked like.
An advertisement for 'Duckies' in this toon is a parody of a contemporary real-world ad for 'Luckies', i.e., Lucky Strike Cigarettes, which were the long-term sponsor of Jack Benny's radio show. (He had better luck with his next sponsor, Jell-O.)
A nice try at a slight variation of the usual Warners formula, and I'll rate this one 7 out of 10.
