Yeah, I know it might sound very unrelated but I was watching the Cantonese dub of "HOUSE MD" (Season 4) just the other day and immediately noticed that Dr. Gregory House has the exact same voice as the Cantonese dub voice of Roy Mustang. Then more familiar FMA voices start to appear. I even heard Envy's voice in another episode of "House" and a few others.
Yes, I know it's on TVB and the dubs for both series are produced by TVB. But just thought I'd give it a mention here.
