Please riff Lionman (as known in English speaking countries) or Kiliç Aslan I have also seen it called. It is a 1975 action movie directed by Natuk Baytan.

Just to show you how bad it is; here is quote from the film --> "What did I tell you? He was raised on Lions milk!".

Synopsis is: When the king is murdered, his baby son and heir is hidden in the forest where he is abducted and raised by a pride of lions. As an adult he uses his beastly strength and claw-like hands to take revenge against the new king and his armies.
