And to bumwhowalks - Batman used a device to shoot his hook, but never a gun. That was developed by the 89 movie. And to be so cheap and take away the credit for designing it while no one did for decades saying "someone else would" is just really changing my opinion about you. He wouldve have some device if something, but this is one of many things developed by the 89 movie. Give the credit where credit is due and take off the hating blinders
		
		
	 
The device that he uses when he fires the rope in the movie is shaped like a gun?!
and I'm just stating the obvious, whoever made the first serious live action Batman movie was gonna use a grappling gun type device, they weren't gonna be doing the Adam West batarang rope climb. 
Just as when Frank Miller did a more realistic and serious Batman in TDKR, he introduced an aspect of bullet-proof body armour, and a gun that fired a rope attachment, credit where it is due, they have all cited the fact that the Miller book was highly influential on the film, and in fact was what revitalised Batman in the comics world, increasing the demand for a serious film to be made. edit: It is possible they got those ideas from the book.
edit: Miller's influence is all over that movie, he was also the first to introduce the aspect of the police and officials in Gotham being corrupt, furthering the need for a Batman, as well as being the first to show BM with bullet proof body armour and a rope firing gun.
edit: Hell, i even said in that last post that if Miller had not included a rope firing gun in TDKR , whoever made the first serious BM movie would have anyway, it was inevitable. Same with BM wearing bullet proof body armour.
edit: Just as Nolan and co would have came up with the memory cloth anyway, if Batman's cape had not turned into a glider in BR. 
I am the one who is being realistic and unbiased in thinking about the artists and their inspirations, and not hanging onto my favourite incarnation of Batman like a deluded fanboy and claiming it came up with everything first.
	
	
		
		
			And just to clarify:
Jerry Ordway: It was from the movie. When I did the movie comic, I was amazed at the various gadgets the prop department created for the film (...) At that time, I also understood that DC was not allowed to use any elements of that specific costume design in the comics, as it was property of the film company. I know they relaxed that rule over the last twenty years, though. (Newsrama.com 2010)
Scott Beatty (The DC Comics Encyclopedia, The Batman Handbook: The Ultimate Training Manual): The Grapnel Gun debuted in the 1989 film, but it didn't really catch on in the comics and become a regular feature in the Bat-Arsenal until it was popularized and used to great effect in Batman: The Animated Series, which debuted just a few years later (Newsrama.com 2010)
Paul Dini: When we did the animated series, we were inspired in part by the tech employed in the movie (Newsrama.com 2010)
		
		
	 
eh, Scott Beatty is talking out of his arse a bit there, after the 89 movie they used the grappling gun a lot in the books, Norm Breyfogyle and Alan Grant had him using it in Detective comics all the time, and yes, in the period of 89-92, before the animated show debuted.
