Makes him more marketable. Hugh Laurie is a "household face" and it's because his American accent is so clean [Blackadder feels like a dream], so this is good news for us because it means he gets more work and not just as the "British Bad Guy" [sexy as that may be].
And I agree with the comments about some Americans' aversion to accents. I've tried to introduce some people to LOUK and heard grumbles about the accents [to which I say, "if you can't understand this, it's because you don't want to, those accents are easy"].
