Jake Gyllenhaal Talks Getting Tased And 'Fifty Shades Of Grey'

Jake Gyllenhaal stars as a Los Angeles police officer going up against a drug cartel in his new movie "End of Watch," and he was so committed to the role that he was willing to learn what it feels like to get tased.

"It was not pleasant!" Gyllenhaal told Us Weekly at the film's premiere on Monday. "Thousands of volts of electricity through your body in a very short period of time was not fun. But ultimately, I can talk about it!"

The actor also did plenty of research for the role that wasn't quite so painful, including going for ride-alongs with members of the Inglewood Police Department -- and things sometimes got a little scary.

On his very first ride-along, they answered a call where someone had been shot and murdered, he told the magazine.

"This was a moment where I think you recognize the absurdity of your own job in light of the situation that you're seeing. I thought to myself, 'What am I doing here, why am I here?' Then I realized we're trying to make a movie that's authentic. It was no joke to any of us, and that made it no joke to me," he explained.

On a much lighter note, the actor also recently said that he would consider taking on the much buzzed-about role of Christian Grey in the upcoming film adaptation of E.L James' best-selling book, "Fifty Shades of Grey."

"Yeah, of course! I always want to work, man, of course," he recently told Ryan Seacrest, adding that he hasn't been contacted about the part but is happy he's being considered. "That's super flattering. I mean, I have not heard that, but if that's true then that's a nice thing. It's always nice to be considered."

Gyllenhaal joins a long list of actors rumored to be up for the part and many have also voiced their interest in playing the dominant billionaire.
