Double Agent 73 is the second film exploitation auteur Doris Wishman made with Chesty Morgan, she of the 73-inch bust. The first being Deadly Weapons (1974). The fact that both movies were released in the same year is an early indication that Wishman didn't necessarily waste a lot of time making them and knocked both out very quickly. Consequently, both these films never remotely betray their low budget origins and are truthfully very amateurish throughout, with the camera-work in particular being of an especially terrible standard. Random objects being focused on is the order of the day here. So there's not a massive amount between both films I suppose but I would definitely opt for Deadly Weapons as being the better of the two, I think it has a better overall focus plus the idea of huge breasts being used as deadly weaponry was a more inspired idea than having them being receptacles for a hidden camera.
I guess you would have to describe this as a sexploitation spy film. It's about a secret agent played by Chesty who hunts down a gang of heroin traffickers. A secret camera is installed in one of her mammoth breasts in order to allow her to gather espionage evidence, unfortunately, if she does not complete her mission within a week the camera will self-destruct, killing her in the process. This story-line is more or less a framework to allow for a lot of scenes of Chesty exposing her huge hooters. Not really a bad idea in principle but it is oddly unerotic to be perfectly honest, which means that events in the story-line become more important. But it's all pretty limited stuff on that front, with the odd unexpected moment such as a bloody murder in a shower appearing out of nowhere to enliven events. But on the whole, this one is only interesting to an extent but certainly of curiosity value at least.
