Mark Wahlberg had a "few confrontations" when he left gang life behind.
The Ted 2 star - who was arrested numerous times in his youth and spent time in jail for assault - realised while behind bars he needed to change his ways and get his life back on track but not everyone supported his decision.
He said: "[It was] just a matter of 'OK, do I want to get high, end up in jail, or focus, get out of here and never look back?
"[There were a] few confrontations [with gang members]."
The 44-year-old actor - who has children Ella, 11, Michael, eight, Brendan, six, and five-year-old Grace with wife Rhea Durham - admits he never imagined he would go on to be as successful, and make his family as comfortable, as he has been with his movie career.
