It didn't do too well last weekend in the US - didn't even make the top ten. The movie really wasn't given enough publicity (Unlike the huge marketing of The Village) and was given many poor reviews, mainly by Thunderbird geeks who made up their mind they were going to hate it before they saw it. I don't think the original Thunderbirds has quite the cult following in the USA that it has in other countries (no merchandising) and so the pester-power from kids was minimal.
