There is a PAL (europe) version of the game.
But don't buy the PAL version! The video on it is not smooth at all
. They didn't convert well the original video footage from NTSC (30 frames per sec) to PAL (25 frames per sec) ... you can see the difference between the PAL and NTSC ... the PAL version is jerky 
There is always a NTSC Japanese version on ebay.com for sale. Get this one 
By the way, there should be a NTSC US version too, but I didn't find it yet.
Thank you for the warning about the bad PAL version, now I'm certain about buying the Japanese version.
It's sad to see that Europe gets a lot of bad PAL conversions, I have a PAL Sega Ages Outrun on the Saturn and it doesn't play smooth either... I bought the Japanese version then and played it on my Japanese Saturn and it plays at full 30fps just like the real deal.
Bruno said it right,
the pal versions of 99% of the european convertions as we know comes from the japanese software companies that realized the game firstly and completely using the NTSC format capabilities (see more spedd at 60hz)
During the last 5 years it must be admited that most of the ps2 convertions has been "a little bit" improved since before where it a real scandal how game were converted and commercialized
The Pal convertion always has expressed:
1) LESS VELOCITY
2) CUT OF THE EDGES
3) BOTTON AND VERTICAL LINES
** 4) CENSORSHIP (Even in the US - but here they use the same Tv system so they did not suffered of the previous defects)
Of course games like arcade's convertions (were velocity means frenetic action= More adrenaline = more joy) as has suffered most of this situation (see Tekken, Sega rally or radiant silvergun)
as not Final Fantasy or RPG Games..

A similar problem is suffering the Pal version of Ps3 if compared to the first japanese PS3
