Gyllenhaal, flanked by "Source Code" co-stars Vera Farmiga, Jeffrey Wright and Michelle Monaghan, was the man of the hour. In the film, he plays Air Force Capt. Colter Stevens, who is on a top-secret mission to save Chicago from a dirty bomb by going back in time -- via a parallel universe called the Source Code -- to discover who blew up a Chicago commuter train (the first in a series of planned terrorist attacks). As a result, he must relive the same eight minutes leading up to the bombing over and over again.
"I found it really freeing," Gyllenhaal said of the experience of acting inside a deeply warped space/time continuum. "A lot of times you stay within the structures and confines of the reality that you're aware of, and in this your imagination could run wild." He also said that one of the fights in the movie was a real fight. 
"Duncan [Jones, the director] said, 'Just go for it'. The fight he's talking about takes place on a train platform and it does look pretty raw". Source: latimesblogs.latimes.com

Plus, Michelle gave five people she'd want to ride on a train with and Jake explained what he'd do for a girl on a first date. (It's actually a pretty cool date idea!)
“He is an army pilot, and he has tremendous training,” said Gyllenhaal last week while promoting the film. “He knows not always to trust his instinct; he knows to trust instruments in an emergency. But somewhere that instinct kicks in. His (human) instinct is saying don’t go this way ... don’t do that. But then he has to listen to his instruments, as he would as a pilot, and keep his cool.”
Gyllenhaal thinks it’s going to be a treat for audiences to watch similar scenes multiple times – each one just a little different, a la “Groundhog Day.” “I found that the exercise in variation, when forced by the constraints of repetition, is fascinating and kept all of our minds always going,” he said of his fellow actors and director Duncan Jones (“Moon”). 
“When we came to doing the scenes on the train and then coming back to it, we made the choice to kind of make each one, each source code, like its own chapter in a book. So each one had its own name, had its own intention. Within each story, we could improv and vary it. We made lots of different choices all over the place.”
“The screenplay was so taut and tight and so strong when I first read it,” he said. “It really started to change when Michelle was cast and when Duncan came on.” Putting a spotlight on the film’s love story was a big question for everyone. “There’s a sort of very emotional romantic aspect to the choice the character makes,” he said. 
“Duncan, Michelle and I worked on that. It was basically a guy who moves from not being able to ask this girl out for coffee to a guy who can ask this girl out for coffee.” He laughed and added, “He has to get blown up a number of times in the process, but it feels like that when you have to ask out somebody that you’re into.” Source: www.enterprisenews.com
Gyllenhaal, who is plays Colter Stevens, is one of the hottest actors out there right now. He’s done drama, action, comedies and romantic films, but “Source Code” combines them all, and adds a healthy dose of science fiction. “The script that Ben Ripley wrote was so well written that it allowed for variation. It allowed us to play with different things at different times,” Gyllenhaal said. “It was really fun for me.
“We tried to think about almost everything. But we didn’t want to answer everything because we wanted the audience to participate.” Monaghan said she and Gyllenhaal had not even met each other before “Source Code.” “We really hit it off,” she said. Source: www.azfamily.com
"Men forgot the men he played. Women, those who could stand the rakish, insulting representations of their supposed heart's desire, whittled their expectations as he tripped from one gorgeous, spoiled, obtuse version of a man to another.

"I like quips," he says. "I like whiffs of cynicism and I think they can be witty. But I don't really know where wittiness is constructive. I also don't think it's half as funny as real behavior — as action, as falling on your face when you're trying to tackle something."
