Mark Wahlberg looked to be in amazing shape as he danced around the ring and exchanged blows with the actor playing Sanchez, real life boxer Miguel Espino. Wahlberg received some movie boxing advice from director David O. Russell when his punches started getting too strong and later was dressed with makeup to make it look like he had received a beating.
