While we're waiting for the live-action adaptation of The Hobbit to figure out what the heck it's doing, here's Hobitit, the 1993 Finnish miniseries that's one of the few live-action adaptations of Middle Earth.
The Hobbit is in development hell, so enjoy some live-action Tolkien to tide you over. Hobitit was a nine-episode miniseries that covered The Hobbit and the LOTR trilogy. It didn't actually take place in Helsinki, but it did depict Gollum as a Finnish man imitating a homeless lime. Here's the subtitled first episode. It's not bad for a modestly budgeted early 90s TV movie — also, please pay heed to Gandalf's totally boss 'stache.
