Three of the most recent Ultra Series films are being dubbed in English thanks to William Winckler Productions.
Tsuburaya has been on a roll during 2016, the 50th anniversary of the Ultra Series. They started the year with a movie based on their latest show, Ultraman X, are currently airing Ultraman Orb, and have a plethora of plans for the future.
SciFi Japan revealed that one of those plans was English dubbing for their recent films, one of which is the aforementioned Ultraman X The Movie. The other two movies are Ultraman Ginga S The Movie and Ultra Fight Victory. The first two films were released theatrically, but Ultra Fight Victory is a compilation film composed of 13 short clips.
The dubs were handled by William Winckler Productions, the company that previously handled the Gaiking, Danguard Ace, and Star Zinger anime compilation films for Toei. Those projects were eventually released by Shout! Factory, but the dubbed Ultraman films do not yet have a distributor.
