Spartacus has UK and US versions. Rocky Horror Picture Show too.
The Deer Hunter (r2) has also a significant cut of about 7 or 9 mins. as compared to the U.S. release, for which reason i decided to get the latter although i really like the bonus features of the r2......
i just ordered
Duel r2 in TIN &
Double Indemnity from amazonUK coz of big price drop but i found out that both their running times are shorter as compared to the r1 counterparts, so i think the british classification board must be really strict
