"Inside Information" has some very mixed directing, with some excellent shots and angles, especially one in a car, but some poor fight scenes, except those with the dog, played by Tarzan.
It has some very mixed acting, except by Marion Shilling and Robert F. Hill.
And with some rather lousy editing, "Inside Information" is ultimately a very mixed motion picture.
Start with a good story: Tarzan, played by Tarzan, is the real hero, and he gets a lot of chances to be heroic. It's been a long time since I saw a dog get to lead the good guys to the bad guys and then himself take down the leader of the bad guys.
Tarzan, the character, really is very smart: He can open doors, despite lacking opposable thumbs, and he can figure out how to get into his partner's office (we dog lovers don't say "owner") even if the door is locked.
Being a discerning sort, he is also quick to detect a shifty character who has fooled all the naive people. (And I have had just such an experience myself, when a carnival barker type was trying, at the motel where I worked, to rent a room to store his clients for a non-surgical face-lift procedure. The owner's dog growled at him! She had never, never growled at anyone. So we knew: No room for that guy.)
Rex Lease is the nominal human hero, but he is out-performed by most of the other cast members, including Robert McKenzie and Victor Potel, as two bumbling private detectives. Potel, co-writer of the story, really stood out even with a clichéd character.
Tarzan got to play two tricks on other characters, one on the detective was hilarious, but one on another dog wasn't. Although, to be honest, it was kind of funny, even if mean.
Charles King actually played a character named "Blackie," and he was a city-slicker bad guy, even wearing a suit and vest. He was really a good-looking guy, and quite athletic. Again he looked as if he should have been hurt in at least one of his fight scenes.
"Inside Information" is fun, and I recommend it, despite its flaws. It's available for free at YouTube.
