Oscars 2016: Why did nine-year-old Room star Jacob Tremblay 'punch' Sylvester Stallone?

Nine-year-old Room star Jacob Tremblay has been an adorable miniature presence all awards season, but he was major trouble for legendary Hollywood action star Sylvester Stallone.

The 69-year-old is the frontrunner to take the Best Supporting Actor Oscar for Creed after the Academy snubbed Jacob in the same category. The kid's alright about it now, but an earlier encounter with Sylvester did get a little tense.

Watch Jacob explaining it to Ryan Seacrest on the Oscars red carpet.

On the bright side, Jacob can take solace in the fact that his onscreen Room mum Brie Larson will probably be getting the Best Actress prize. We all know she has Jacob's vote.
