It surprises me that no one has mentioned the 1966 BATMAN movie, which seems the most obvious. You could say that it's just the same as the BATMAN TV show, but it was a theatrical release--coming out on my birthday in 1966. And it had features peculiar to it (like the ganging up of the villains) that set it apart from the TV show. Also it seems like people more often quote that movie than individual TV episodes. And with the rights disputes over the TV show, you were more likely to find an official copy of the movie for sale in video stores. It never went away.
Even though the camp TV show might have had some effect on what kinds of TV shows followed, we still got a steady stream of super-hero TV shows in the 1970s. Whereas, the camp image of Batman was a big problem in getting any movies made. The 1978 SUPERMAN movie had to struggle with the shadow of camp. It took decades to get a new Batman movie made precisely because the camp Batman was still so prevalent for most people.
