Dueling Dubs: Well there's the Los Angeles dub for the TV series. The Vancouver (aka the one in BC, Canada) dub is done for the OVA version and the Southeast Asian dub for Southeast Asian countries that aired in Animax at the time (e.g. Philippines, Malaysia, Singapore).
Hey, It's That Voice!: In the English dub, Batou and Chief Aramaki carry over their voice actors from the 1995 film.
Screwed by the Network: The show can be considered a victim of this during its run on the revived Toonami, as it was unceremoniously removed from the lineup to make room for InuYasha. Fortunately, the Toonami crew have confirmed that the show's removal is only temporary and that it'll come back in the future.
