The fans have spoken, and they love Baby Groot.

"Holy crap! With 81 million views in its first 24 hours, the Guardians of the Galaxy Vol. 2 Teaser Trailer is the SECOND BIGGEST TEASER TRAILER EVER (after Beauty and the Beast), and the biggest Marvel Studios Teaser ever!," exclaimed Gunn on his Facebook page. "No kidding - I'm, like, floored. Thank all of you so very much for watching it (more than once), and sharing it, and welcoming Baby Groot and Mantis with open arms."

Gunn goes on to thank CCXP in Brazil, where the trailer debuted, along with Marvel and Disney's marketing departments "who put up with all my eccentricities during the teaser editing process. Honestly. You guys can't imagine what they deal with. I'm a maniac. Now they're gonna have to deal with it again as we prep the FULL TRAILER..."

Another example of the power the "Guardians of the Galaxy" brand commands is getting "Fox on the Run" by Sweet, which was the song used in the teaser, to number one on the iTunes Rock chart.

Opening May 5, “Guardians of the Galaxy Vol. 2” also stars Chris Pratt, Zoe Saldana, Dave Bautista, Bradley Cooper, Michael Rooker, Karen Gillan, Sean Gunn, Glenn Close, Elizabeth Debicki and Chris Sullivan.
