Stuntman and actor Emilio A. Messina was born in Casablanca, Morocco on February 24th 1936. He died on April 21st 2007, aged 71. His wife was called Incontrata and he had a daughter, Stephanie, a son, Gabriele, a sister, Lidia and his stuntman/actor brother Roberto, with whom he had a pretty much parallel career. 
Both Messina brothers began their film careers at the start of the 60's as stuntmen in peplum movies, often but not always working together. When those faded out they proved equally adept through the cycles of eurospies, spaghetti westerns and police buddy movies.
The brothers both moved to Miami, Florida in 1982, after which they only made a few more odd movies, most of which were Italian productions shot in Florida. They were still resident in Florida at the time of Emilio's death. 
Emilio always stood out from the pack of peplum stuntmen being the burliest and hairiest of the lot. With only two exceptions he had some sort of facial hair in all of his films, which helps as an aid to identifying him. I continue to find uncatalogued appearances from Emilio in all genres, so I am certain there will be additional titles being added to his filmography.

A little more Emilio!
There are still a few movies where Emilio is credited by various online sources that I have been unable to find, so if anybody has images of Emilio in the films below you know ahat to do.
- Agente segreto 070 - Thunderbay missione Grasshopper (1966) (maybe credited)
- Il magnifico West (1972) (maybe credited and master of arms)
- Esecutore oltre la legge (1974) as Steig (maybe credited)
- Noi non siamo angeli (1975) as Shark henchman (maybe credited) - image on CIDb
- Il pentito (1985)
- Bersaglio sull'autostrada (1988) - beware of another film named Moving Target from the same year that comes up in searches for this one.
Messina is missing!
As often seems to be the case we also have a selection of films where Emilio is credited by some online resource, but where I have been unable to find him. I may have missed him in some, while in others he has been misidentified, mistaken for his not-at-all-look-alike brother or simply mysteriously does not appear. In all these titles he is uncredited.
- Se incontri Sartana prega per la tua morte (1968) credited on IMDb as playing a Tampico henchman. I've looked and couldn't see him.
- Spara, Gringo, spara (1968) IMDb says he is credited under the pseudonym of Van Lanen and plays Soldier in Doneghan's army. I haven't found him but need to look more closely at this title.
- Il giorno del giudizio (1971) Does not appear. Credited on CIDb as playing a poker player, but the image accompanying the credit is of brother Roberto, and it is Roberto who appears in the role in the film, not Emilio. (I have now corrected this on CIDb in case you are looking and can't see it)
- Giubbe rosse (1975) credited on CIDb as One of Wolf's men. I've looked and didn't see him but again I need to give this one a closer look.
- La via della droga (1977) Listed on IMDb with no role given. I couldn't see Emilio, but there is a similar-looking unidentified actor who he may have been mistaken for.
- Un poliziotto scomodo (1978) Listed on CIDb with no role given, this looks like another case where he has been misidentified for brother Roberto - who does appear but is missing from CIDb.
- Non sparate sui bambini (Squadra antisequestro) (1978) Emilio reportedly should have a credit in this one for "Collaborazione alla regia", but the English language/Greek subbed copy I saw only had minimal credits. If anyone has an Italian copy please check.
- Sangraal, la spada di fuoco (1982) Listed on IMDb as playing Nantuk's warrior, but while there are a number of roles that could fit this description, none of them vaguely resembles Emilio.
