A UK PS3 will NOT play DVDs from the US. UK DVDs are Region 2 while US ones are Region 1. Unless you make your PS3 multiregion, and I'm not entirely sure how to do that, the answer is no. This applies not just to the PS3, but with all DVD players in general. Some DVD players have a numeric code which you enter to unlock them, others can be bypassed via infra red remote control which some companies send out, just to unlock the region coding. Hope that helps!
