If you can find one (mine is a R2 NTSC import from Japan), the Version Integral is the one to get. This is the original Luc Besson cut and shows Matilda & Leon on her training missions. This was cut from the UK release on DVD & Video I think also in the cinema. Crucial to the plot is the explanation of the ring trick which makes Gary Oldman's last scene more complete. Only downside is that there is no menu, scene selections or extras at all.
