Do American DVD's still play on UK DVD players?

I have a serious problem, I just purchased a dvd via the internet and have only realised that it’s region 1 and is from America, will it work on my British DVD player?
Help much appreciated.

Usually no, but there are ways to circumvent this with region killers etc.

(Your use is legit, since you paid for the DVD)

Chips or buy a region free DVD player.
