Still trying to reach some conclusions on the missing footage based on researching past releases. Here is a comparison of the sections of the beating scene that were cut between a variety of releases: Grey=missing footage. As far as I can tell, the missing dialog portion was removed from American releases in 1997. It was always a part of the 1980's uncut releases. It was also part of the 1991 laserdisc which was a scan of a heavily cut 1967 UA release print (other sections of the beating were cut but not this dialog). As far as home video releases are concerned, the dialog only disappeared in 1997 when MGM tried to blend the Italian and English versions. It has been missing from all North American releases since. Apparently this scene was originally dubbed into three different languages. Italian in 1965, and English and German in 1967. It appears on every Italian and German home video release from the 1980's until now, but is not currently part of the Italian negative.
