It's still six months away from hitting theaters, but the trailer for "Guardians of the Galaxy: Volume 2" is already burning up social media. The Guardians of the Galaxy Facebook page dropped the new trailer Saturday evening and within 3 hours it was viewed more than nine million times. The trailer doesn't give much of the plot away, except for a mention of an Atomic bomb, but it does re-introduce the team of Star-Lord, Gamora, Drax and Rocket, as well as a scene-stealing Baby Groot. You'll recall Groot sacrificed himself at the end of the first "Guardians of the Galaxy" to save his friends from certain death with his last words "We are Groot" bringing us all to tears. And in the first few moments of the trailer, we get to revisit our wonderful woodland alien as a baby Groot with his words "I am Groot." The second installment of "Guardians of the Galaxy" opens in May of 2017.
