Preliminary work has begun on two Hollywood films dealing with the Boston Marathon bombings. Actor Mark Wahlberg has been in town this week to spend time with Danny Keeler, the real-life Boston cop he’ll play in “Patriots Day.” Among the stops Wahlberg, the movie’s director Peter Berg, and Keeler made Wednesday was the Eire Pub in Dorchester. The night before, we’re told, Wahlberg met with the family of Martin Richard, the youngest victim killed in the April 15, 2013, bombings. Keeler is a veteran Boston Police detective who was in command at the marathon finish line and was instrumental in the subsequent hunt for the Tsarnaev brothers.

Meanwhile, we’re told that Jake Gyllenhaal also has been in the area in recent days to spend some time with bombing survivor Jeff Bauman. Gyllenhaal is set to play Bauman in “Stronger,” director David Gordon Green’s movie based on the book by Bauman, who lost his legs in the attack. “Orphan Black” actress Tatiana Maslany is playing Erin Hurley, who was Bauman’s girlfriend at the time and is now his wife.
