Not sure if this is the best place to mention this, but I've recently synced the original, absent from DVD English dub of The Mysterians (1957) to a widescreen version. It's up on MySpleen as a DVD5 torrent right now.
The new dub is a 5.1 remix (with few intrusive new sound effects, thankfully), but the voice talents are all Anime dubbing people and they're really lousy in comparison to the talents of folks like Bret Morrison in the original.
