Leslie Knope will be rubbing elbows with some very powerful Washington players when "Parks & Recreation" Season 5 premieres.

In a behind-the-scenes video, the comedy's stars talk about filming with Senators John McCain, Barbara Boxer and Olympia Snowe. "We shot today with Senator McCain, one of my old acting buddies," Amy Poehler says in the video. "He and I have worked together before and he was great."

"We get actual scenes with them where they're being hilarious," Adam Scott says. "And I have a feeling that they will be more hilarious than me."

The video also includes interviews with Chris Pratt and Aubrey Plaza, as well as some pretty hefty promises from Poehler.

"Parks & Recreation" Season 5 premieres Thurs., Sept. 20 at 9:30 p.m. ET.
