I love videos on YouTube where people locate and revisit movie locations. It's so interesting to see how different places look without all the lighting, props, set dressing and actors. With Batman Forever there's only so many real locations to revisit because so much of the movie was shot on soundstages.
Here's a very cool video from a YouTuber called Pat the Batman Fan who managed to track down the exact alleyway used in the sequences where Two Face and his goons chase Batman into a dead end. It's a fantastic, funny, fact filled video, check it out.
