You might want to slow down on those popcorns and soda because the upcoming Avatar sequel is reportedly more than THREE hours! 

Aptly titled Avatar: The Way of Water, the James Cameron-directed film is slated for a Dec. 16 release. It features the leading stars from the original 2009 adaptation, including several new line-ups.

  
And speaking of the lengthy runtime, Cameron's already got an amusing comeback for the incoming comments-

"I don't want anybody whining about length when they sit and binge-watch [television] for eight hours. I can almost write this part of the review. The agonizingly long three-hour movie. It's like, give me a f*cking break. I've watched my kids sit and do five one-hour episodes in a row."
