First time PS3 buyer

[manasecret]

Ok, first, the backstory.

My birthday is on August 30. I recently bought a very nice LCD HDTV when our other tube TV died a little over a year after buying it. I am very happy with my HDTV, but I have yet to get a Blu-Ray player all the while wishing one would just arrive magically on my doorstep. So as a gift to myself on my birthday, and since Sony was so nice as to knock down the price on their new PS3 Slim, I'm splurging.

So, my question to you:

I want to buy one game and one movie to start off. While I expect to be renting Blu-Ray movies from now on, I don't expect to be purchasing or renting any games for a long time after I get the first one. I'd like both the game and the movie to be a showcase for the TV. I'd also like them to be a decent game and a decent movie!

So, for those of you with a PS3 and/or a Blu-Ray player, if you had to go back to the beginning and, knowing what you know now, start all over again -- but you could only choose one PS3 game and one Blu-Ray movie to show off your HDTV -- what would they be?

EDIT: And to keep it interesting for you 360 players out there, do you think that even though the 360 doesn't have a Blu-Ray player I should get it over the PS3? What would be the first and only 360 game you would buy?
