No biographical details are currently known.
I have found a couple of undocumented appearances by Antonio, so there are probably more.

- Tío, ¿de verdad vienen de París? .... Jealous man in nightclub (uncredited)
- Curro Jiménez (1977 TV series) S. 2, Ep. 7: "Entierro en la serranía", IMDb. I have checked this episode, but I was unable to recognise Antonio and the credits were cut. Maybe someone else will have better luck?
- Esa noche (2005 short film) IMDb says "Antonio Peral" is credited, but his one-off appearance in a short film 28 years after his last role would seem highly unlikely.
- All'ombra di una colt (1965) IMDb as Blacksmith. The actor playing the blacksmith is not Peral, maybe confused with I due violenti where he does play this role.
- Finger on the Trigger (1965) IMDb as Tom Sharpe. There is a "Jose Peral" credited, but Antonio does not appear and there is no "Tom Sharpe" character - agreed by Carlos.
