I'd LOVE to see the OT in Japanese or Russian.

I own an officially released Japanese OOT DVDs (GOUT), it's still available at amazon.co.jp, hmv.co.jp or any other japanese DVD-store.

Star Wars presented with two dubbed tracks -- original '78 dubbing and a newer one. ESB and ROTJ offer new dubbing only.

You can watch few scenes from EpIV and EpV SE 04 here:

As for Russian dubbing -- there's two dubbed versions of Star Wars:
1. A very well done Soviet dubbing shown in USSR theaters back in the late 80's.
2. A made-for-TV dubbing (and I mean dubbing, not a voiceover) done by ORT TV-channel in 2005 (along with ESB and ROTJ) as part of the ROTS promotion. Pretty lame for my tastes -- poor acting and questionable translation work.

Original Star Wars dubbing is almost impossible to find now, and those few collectors who own it on film do not want to share.

ORT-dubbing of OT SE 04 can be easily found via Internet.

Here's two short samples:
Vader and Leia at Tantive IV (SW)
Vader and Jerjerrod at Death Star II (ROTJ)
