The 41-year-old star plays the lead role in the new biopic movie about Sam Childers, a biker who finds God and becomes a crusader for Sudanese children.
According to OK!, he told reporters: 'I mean, listen, you do a movie like this and you get into a few accidents. I ripped a tendon here [points to groin] in the same scene when I am running to save the kids.
'It still is an issue and then I was shot twice in the head by Souleymane [Sy Savane].'
He added: 'It was a shell. I know, it sounds better to say shell, but the shell hit me and I was pouring with blood.
'Finally about 20 minutes later we got the bleeding to stop and then another shell hit me within half an inch of the first one. Slit my head again and then I realised it was an issue with where I was standing.'
