London: Scottish actor Gerard Butler says he is finding it hard not to weep during interviews as he promotes his new movie `Machine Gun Preacher`.
The 41-year-old plays a real-life Sudan hero Sam Childers in the film and said it`s becoming difficult for him to recall the time spent on the set of the film in South Africa without crying, Daily Star reported.
"This happened to me a lot when we were filming. I would just be overcome. I feel every emotion. I haven`t talked much about this movie in a while, and I did the other day, and I just started crying. I cried for about five minutes," Butler said.
Childers transformed his drug-riddled, crime-filled life after finding God and founding an orphanage in war-torn Sudan in 1998.
"A lot of the feelings I felt with Sam, the violence and the craziness, being out of control and not knowing how to live your life, I had all that. Did I go around stabbing people and shooting people? No. Did I end up in Africa building an orphanage? No. But I did have a massive transformation in my life where I sorted everything out," he added.
