Reminded me of Batman
I would have bet money this was directed by Leslie Martinson, who helmed the 1966 Batman movie and episodes of the TV show, but it wasn't, even though it is completely in the style of the show.
Especially the fight scene near the end with Kurt Russell and a bunch of men old enough to be his father (whom he could have beaten without the secret formula). The music was very Batmanish; all that was missing were the "Pow!" and "Zing!" graphics.
And the scene where the men are on top of the building and sneak onto the window washer scaffolding, reminded me of all those times B&R scaled buildings. Of course of of those men was played by Cesar Romero, so that's really what drove the Batman theme home.
