National Geographic is unveiling “Untamed Americas” tonight at the Uptown Theater. Following the screening will be a reception at the National Zoo. FishbowlDC is giving away three pairs of tickets to the first three people who correctly answer our weirdo animal trivia question. The screening begins at 6:30 p.m. The reception starts at 8 p.m.

Actor Josh Brolin narrates the series. He unfortunately won’t be attending as he’ll be working on another film. Producers of the series and other usual suspects will attend.

What you can expect from the film: “An intimate look at some of the greatest wildlife spectacles and against-the-odds fights for survival ever captured on camera. Soaring mountains, burning deserts, tangled forests and curvaceous coasts. A grizzly bear takedown of helpless elk calves in Yellowstone. Bighorn sheep going head-to-head in battle. Giant Humboldt squid cannibalizing their kin. Puma cubs hunting solo for the first time. The landscapes and wildlife of the Americas are savage, shrewd and stunning.”

Those who don’t win the contest can still watch the premiere of “Untamed Americas” on June 10th and 11th at 9 p.m. ET/PT on Nat Geo Channel.

THE CONTEST: Let’s get down to business. Send your answer to the following question to FishbowlDC@mediabistro.com or to Betsy@mediabistro.com. The rules are simple: First three people to answer correctly win. Don’t forget to include your full name, where you work and phone number.
