One way to get to know a town is through how it's depiction in art - here are some links and information on movies, books, songs, TV shows, etc about Baltimore that I'm familiar with:

• Movies
  • Barry Levinson:
    • Diner
    • Tin Men
    • Avalon
    • Liberty Heights
  • John Waters
    • Hairspray
• Music
  • ??
  •  
• Books
  • Laura Lippman
    • Baltimore Blues - first Tess Monaghan mystery - fun to read for the baltimore information, but kind of lame otherwise. I'm not a big fan of mysteries, but even I could tell this wasn't a first-rate effort. The characters show promise, however some are pretty stock.
    • Charm City
    • Butchers Hill
    • In Big Trouble
