Most available sources give his date of birth as September 2nd 1928 in Rome.
Gino Marturano has said in an interview that he was in a concentration camp along with Benito in 1942, when they were both still children.
His earliest confirmed role comes from Senso (1954), although he reportedly also appeared in Ulisse the same year and Ben-Hur (1959), but we were unable to identify him in our topics for these films. He then worked steadily through the 60's, 70's and 80's, being mostly associated with the peplum and western genres. His last-known appearance came in 1991.
Benito died in Rome on December 18th 1999, aged 71..
I have started his topic only with images I already had saved, so there are plenty of roles to be added. I have included a second filmography to add his production credits. It seems he appeared in many of the films where he has production credits, so it's always worth checking.

- Ben-Hur (1959) Listed as appearing in production lists, but not found in our topic for this film. Chances are that he is in there somewhere amongst the hundreds of extras, but maybe does not appear identifiably.
- L'ultima carica (1964) IMDb
- Circuito chiuso (1978) - here he's appearing in the movie theatre onscreen, apparently from "E per tetto un cielo di stelle"
- Ulisse (1954) IMDb as Elatos. We failed to identify him in our topic for this film and this character is nowhere to be found.
