Josh Brolin told OnTheRedCarpet.com that he studied Tommy Lee Jones "for months" to play a younger version of his character in "Men in Black III."
"Because I knew Tommy, I was a little - it was exciting - but I was less nervous than I probably would have been," Brolin told OnTheRedCarpet.com in a recent junket interview. "It was abject fear that I was feeling in the beginning and I wanted Tommy to like it... probably not a great career move on my part? Just the idea of doing something that could've failed miserably. I'm just glad I didn't get in the way of the movie. I'm happy about that."
Both Tommy Lee Jones and Will Smith reprise their roles as Agent K and Agent J from the first two "Men in Black" films. In this film, Agent J travels back in time to 1969 to help save a young Agent K - played by Josh Brolin - as well as planet earth.
In order to portray Jones, Brolin studied the Oscar-winning actor for months to get down the nuances that make the 65-year-old actor a legend.
"Lots of YouTube, lots of Hulu, lost of Netflix, lots of DVD, lots of Garage Band [the apple application] for me, just playing it back and playing it back. So, hours? No. Days? No. Months. Months. But I finally think I got something," Brolin continued. "You know there's an essence of Tommy that I didn't realize was as elusive as it is and I think finally when I first started watching the first movie over and over and over that something started to click a little bit."
Smith agreed that Brolin nailed the role and told OnTheRedCarpet.com that the success of the movie lay on the shoulders of the "No Country for Old Men" star.
"Josh Brolin, the whole of the movie rested on his portrayal of Agent K. If he didn't deliver Agent K in a believable way, the whole movie falls apart," Smith told OnTheRedCarpet.com. "It's funny because he did it so well, that it actually disappears. You even forget the level of performance that he's given... If Agent K was a real live character, Josh Brolin would get an Academy Award nomination for his portrayal of Agent K."
Brolin's biggest critic was his wife, Diane Lane who he married in 2004. He said the actress was a big fan of the first movie, so he had to try hard to win her over.
"It is emotional. It has a weight to it. It's really nice. It's got a lot of heart to it," Brolin said of the film. "Somebody told me recently - oh! - it was my wife, who said: it's impossible to compete with 'Men in Black 1.' I like this one better. 'Cause it's got everything, which I think is really cool. You're going to say that when you're promoting a movie anyway, but when you actually believe it, it's much easier to say it."
The "Men in Black" franchise kicked off in 1997 and a sequel hit theaters in 2002. On Friday, the third installment earned $18 million in the box office.
The film hit theaters on Friday, May 25. Check out the trailer for "Men in Black III" below.
