Turkish Star Trek
Turkish Star Wars
Turkish Wizard of Oz
These aren't parodies of American films, nor are they really films themselves. Most of them simply rip off footage from American movies and spice in scenes with Turkish actors. I assure you that I have been assured that these are real Turkish films released in the 1970's and 1980's. Apparently, Turkey was in a period of tremendous political upheaval, so it was difficult to import actual American films (from Wikipedia). As a compromise, well, we got this.
First, Turkish Star Trek:
This is the first part of Turist Ömer Uzay Yolunda. This was released in 1973 as part of the popular comedy film series Turist Ömer (the last part, incedentally), so this one actually was a parody. Still, if you saw for the first time, you'd think it was a rip off. You can watch all nine parts on YouTube at your discretion, and you can read more about it here.
Turkish Star Wars:
These are the beginning (sorry about the French subtitles) and ending scenes of Dünyayı Kurtaran Adam. I especially like the inclusion of Disco Battlestar Galactica. It gives it a ring of authenticity. You can read about it here and here, and if you really want, you can watch the whole frakkin' thing on Google Video.
Turkish Wizard of Oz:
Read about it here and here.
Read about it here.
You can read more about this one here.
Finally, I'll show you a video made by a single visionary, Albert Wikowonkavitz, trying to revive this brilliant cinematic legacy. Enjoy!
