Well, it turns out this particular bit of information was untrue. Odd that it was also mentioned on actress Edwige Fenech's facebook page (and has since been removed). A thread about it can be found here...
It's relieving news that Hilton is still alive, but frustrating that individual(s) would spread that he has died. I'll still leave this mini bio of Hilton up although I've tweaked it slightly.
Hilton was born in Uruguay July 16th, 1934. After featuring in a large number of showbiz productions in his homeland, Hilton moved to Italy in the early 1960's where he would soon find himself extremely busy featuring in films such as THE MASKED MAN AGAINST THE PIRATE (1964) and DESERT BATTLE (1969). But it was his spaghetti westerns that brought Hilton the most recognition abroad.

Hilton painted a wonderfully memorable picture of himself in the film MASSACRE TIME (1966) for director Lucio Fulci. In that film, Hilton successfully stole the show totally away from then burgeoning mega star, Franco Nero. George played his drunken gunslinger, Jeff Corbett, to the 'Hilt' (haha) creating a lively and fun character that likewise rivaled the sadistic villain essayed by Nino Castelnuovo. Hilton would soon become associated with comedic roles in his westerns. He occasionally got the chance to shine in a serious role and arguably none were as stunning as his tragic hero in A BULLET FOR SANDOVAL from 1969. More westerns followed and when THEY CALL ME TRINITY (1970) begat a surge of comedy westerns, Hilton was there to partake in a slew of like minded oaters such as HEADS I KILL YOU...TAILS YOU'RE DEAD! THEY CALL ME HALLELUJAH (1971) and its sequel. He also headlined the two slapstick westerns, ONCE UPON A TIME IN THE WEST...THERE WAS A MAN CALLED INVINCIBLE (1973) and its sequel, THE CRAZY BUNCH (1974). Other Hilton westerns include ANY GUN CAN PLAY (1967) and THE GREATEST ROBBERY IN THE WEST (both 1967), THE RUTHLESS FOUR and THE MOMENT TO KILL (both 1968).

Like most popular European genre actors, Hilton made the transition to other Italian styles of cinema such as crime pictures with SEVEN HOURS OF VIOLENCE (1973) and BLAZING FLOWERS (1978). He also featured in a handful of Giallo movies such as CASE OF THE SCORPION'S TAIL (1971) and MY DEAR KILLER (1972) among several others. He has a cult following in the United States and even moreso overseas.
