On the set of "White Collar," which returns to USA with new episodes Jan. 18, "There are no plastic water bottles. We have water coolers and everybody uses their canteens," says Matt Bomer, who installed an Aquasana water filter at home "rather than have 400 plastic water bottles around." He also makes "a really concerted effort to eat organic meats and eggs, for my health, and to know that the animal was treated humanely and was not filled with hormones and antibiotics." Co-star Tim DeKay, a longtime Prius driver and supporter of the California Environmental Fund, recently bought carbon offsets when his family flew to London for a vacation.

Coming up in the new episodes, DeKay's FBI agent Peter Burke and Neal Caffrey — the crook-turned-consultant Bomer portrays — "take on different roles," says DeKay, who loves the humor and complexity of his law-and-order character, who "sometimes can go to the other side to solve a case."

"We go back in time in flashbacks so you see the genesis of the relationship, how we first met," adds Bomer, noting that the story will reveal more about the mysterious music box and love of Neil's life, the enigmatic Kate. He promises closure to "a lot of really big mythology questions," but admits he doesn't like to know too much in advance about where the plot is going. "I just say. 'Tell me what I have to know.' That way every time I get a script it's like a [skipwords]Christmas[/skipwords] present that you open and you just take the journey."

Bomer recently completed a role in "Now," a thriller from "Gattaca" director Andrew Niccol set in a futuristic society where the aging gene is turned off at 25, time is currency, and only the rich get to live long lives. He stars opposite Justin Timberlake, Amanda Seyfried, Cillian Murphy and Alex Pettyfer as "a 105-year-old from the very upper class. He knows that the way society is set up is inherently wrong but doesn't know how to change it. He wants to effect change but he doesn't know how to do it and is sort of lost." It will be out next fall.
