Only if such an original exists. Or still exists.
Question 1 would be: Why did they show not a longer Version at Venice, if there is one? Film Festivals tend not to show cut movies.
The Venice version seems to be the same as the Rai version, even if there is a small runtime difference of a min. Maybe only a wrong data.
Question 2 would be: Where was the TV version with the extra minutes sourced from? Or wasn't it a TV version, but an Italian VHS version?
Question 3: Was El puro released in Italy on VHS?
