Someone already mentioned the original Jules Verne, so might as well throw out The Secret Adventures of Jules Verne, the Canadian TV series. It was a bit uneven, but great fun. Wild, Wild West - either film or television series - could count as steampunk as well, but I don't know how keen you are on that particular environment versus a more urban one.

You can also try any number of Sherlock Holmes pastiches: the Sherlock Holmes Mysteries graphic novels take a sort of LXG approach, pitting Holmes against various Victorian-era characters.

Hope that helps!
